Carbomer is a commonly used thickener, widely used in industries such as cosmetics, pharmaceuticals, and food. This article will delve into why carbomer can thicken and help you better understand this important substance.   1、 The structural characteristics of Carbomer   Carbomer is a natural organic polymer compound composed of multiple polymer chains. Its molecular structure contains multiple hydroxyl and carboxyl groups, which give carbomer high polarity and water solubility. These characteristics provide a foundation for the application of carbomer in thickeners.   2、 The Thickening Principle of Carbomer   The thickening principle of carbomer is mainly based on the multiple hydroxyl and carboxyl groups in its molecular structure. These groups undergo ionization in water, causing the carbomer molecules to charge and attract surrounding water molecules. When the concentration of carbomer reaches a certain value, these charged molecules will crosslink with each other, forming a three-dimensional network structure, thereby playing a thickening role. In addition, the molecular chains of carbomer are longer and more prone to entanglement, further increasing the viscosity of the system.   3、 Thickening effect and influencing factors of carbomer   The thickening effect of carbomer is influenced by various factors. Among them, concentration is a key factor. As the concentration of carbomer increases, the number of crosslinking points between molecules gradually increases, the network structure becomes more stable, and the viscosity of the system also increases. In addition, temperature, pH value, electrolyte, etc. can also affect the thickening effect of carbomer. For example, at higher temperatures, the movement of carbomer molecules intensifies, which may lead to network structure damage and a decrease in viscosity; Under acidic or alkaline conditions, the charge properties of carbomer may change, which may affect its thickening effect.   4、 The application of Carbomer in various industries   Cosmetic industry: Carbomer is mainly used as an emulsifier, thickener, and stabilizer in cosmetics. It can increase the viscosity of the product, improve the texture, prevent layering and sedimentation, and also enhance the stability of the product. It is widely used in lotion, face cream, eye cream and other cosmetics.   Pharmaceutical industry: Carbomer is mainly used as a suspension aid in pharmaceuticals. It can increase the suspension stability of drugs, prevent drug precipitation or stratification, and improve the bioavailability of drugs. It is used in both oral and injectable medications.   Food industry: Carbomer is mainly used as a stabilizer, thickener, and suspension agent in food. It can improve the taste and texture of food, prevent food sedimentation and layering, and also extend the shelf life of food. It is applied in foods such as fruit juice, beverages, and seasonings.   5、 Conclusion   Carbomer, as a natural organic polymer compound, has excellent thickening properties. The thickening principle is mainly based on the ionization of multiple hydroxyl and carboxyl groups in the molecular structure in water, forming a three-dimensional network structure. The thickening effect of carbomer is influenced by various factors such as concentration, temperature, pH value, and electrolyte.

It can anticoagulate blood samples for a short period of time, ensuring that a series of tests are carried out in an orderly manner and providing effective basis for test results. This article will introduce the synthetic raw materials and basic information of heparin sodium anticoagulants.   Raw materials for heparin sodium   Heparin sodium is a natural biopolymer substance. The main components of heparin sodium as a blood vessel additive are lung adenosine, mucopolysaccharide, gelatin, and adenosine. Among them, lung adenosine is the main raw material of heparin sodium, accounting for more than 60% of the finished product of heparin sodium. Lung adenosine is a polymer extracted from animal tissues, and pig lung adenosine is currently the main raw material used in the production of heparin sodium. The additive heparin sodium for blood collection mainly comes from animal liver, especially pig liver.   In fact, there is also heparin in the human body, but it exists in the form of ions in the blood. It is an important anticoagulant substance in the human body that can effectively prevent blood clotting and thrombosis. It is one of the important factors for maintaining normal blood flow and circulation.   Preparation of heparin sodium   The production process of heparin sodium is divided into steps such as raw material preparation, extraction, refinement, synthesis, and purification. The specific steps are as follows:   1. Preparation of raw materials: Mix pig lung adenosine, mucopolysaccharide, gelatin, and adenosine in a certain proportion to prepare them as raw materials for heparin sodium.   2. Extraction: Add the mixed raw materials to the acid solution and hydrolyze under high temperature and pressure to produce heparin polysaccharides.   3. Refinement: Further purification and separation of heparin polysaccharides are carried out using processes such as precipitation, filtration, and purification.   4. Synthesis: The refined heparin polysaccharide is subjected to a series of chemical reactions to synthesize high-purity heparin sodium.   5. Purification: The synthesized heparin sodium is subjected to final purification treatment to remove harmful ingredients and impurities, and is powdered for easy use and storage.   6. Quality control: Conduct strict quality control to ensure that the quality of the product meets the final requirements.   Advantages of heparin sodium   1. Significant anticoagulant effect: Heparin is an efficient anticoagulant that can effectively inhibit blood coagulation and prevent thrombosis.   2. Low interference with blood cells: Heparin has little interference with blood cells, does not affect the size and morphology of red blood cells, does not cause hemolysis, and is suitable for various blood tests.   3. Convenient storage: Heparin anticoagulants can be stored at room temperature without the need for refrigeration, making them more convenient to use and store.   4. Safe and reliable: Heparin has high safety and reliability in clinical application, and the risk of allergic reactions is low. Application of Heparin Sodium   The previous text introduced many advantages of heparin sodium, so it is often used in the detection of whole blood samples.

When it comes to measuring uric acid, you understand everything. Once the uric acid level in the body exceeds the normal range, it can trigger gout at any time. The new Trinder's reagent produced by Desheng is the preferred choice for in vitro diagnostic kit manufacturers. Due to its simple and convenient operation, fast results, it can help doctors better diagnose and treat related diseases, and also guide patients in self-management and prevention of complications.   Generally speaking, men have a uric acid value greater than 420 μ Mol/L, female uric acid value greater than 357 μ Mol/L, can be diagnosed as hyperuricemia, broadly defined as gout. Gout, gout, just listen to the name, it feels like it's going crazy in pain. The pain during gout attacks is very obvious and quite severe. The new Trinder's kit can also be applied to study the role of uric acid in the occurrence and development of diseases, providing strong support for scientific research in related fields. In summary, the new Trinder's kit is a highly sensitive and accurate uric acid detection kit widely used in clinical laboratories, which helps to improve the accuracy and efficiency of uric acid detection.   Uric acid is an end product of purine metabolism, and its detection is of great significance for diagnosing diseases such as gout and renal insufficiency. So once an increase in uric acid level is detected, it is necessary to take preventive measures. Otherwise, if it develops into gout, it is necessary to be prepared to receive the baptism of pain at any time and to control one's diet for a long time, because gout is irreversible. Gout is so terrifying, so especially for men, they should pay more attention to their dietary habits and undergo regular uric acid testing. It is generally recommended to test at least every 3-6 months. For patients with more severe conditions, more frequent testing may be necessary. At the same time, it is also recommended to conduct uric acid testing to evaluate the effect when adjusting lifestyle such as diet and exercise.   The new Trinder's reagent kit is an efficient and sensitive kit for uric acid detection, which uses more advanced chromogenic agents to replace phenol, significantly improving the sensitivity of the reaction. The principle of use in in vitro diagnostic kits is: the tested substance produces hydrogen peroxide through enzymatic action (i.e. serum, plasma, or urine samples), and hydrogen peroxide under the action of 4-aminoantipyrine and peroxidase, It can cause the chromogen substrate to generate quinone imine compounds. By changing its color and following the instructions for use, the uric acid level in the body can be determined, thereby determining whether there are abnormalities in the body.   The new Trinder's reagent produced by Hubei Desheng can not only be used to detect uric acid, but also as a detection reagent for creatinine, cholesterol, and triglycerides.

Serum separation gel is a special additive for blood collection that has viscosity and can form a gel like isolation layer under the action of centrifugal force, separating serum and blood clots, in order to better preserve serum and improve serum yield.   The method of flipping the serum separation gel is mainly during the centrifugation process. Usually, during the centrifugation process, the test tube is placed in a centrifuge, and the centrifugation speed and time are controlled to flip the serum separation gel under the action of centrifugal force.   When it comes to flipping, it has to be said that if the serum separation gel is not flipped, it may cause a series of problems. The serum and blood clots are not completely separated, and there may be impurities such as red blood cells and white blood cells in the serum, which affects the quality and purity of the serum.   Secondly, there may be residual coagulation factors such as fibrinogen in the serum, leading to incomplete blood coagulation and affecting the accuracy of experimental results. The most important thing is that the serum separation gel does not flip, which leads to separation failure and requires re collection of blood samples, increasing patient pain and medical costs.   Therefore, not flipping the serum separation gel is an abnormal phenomenon that needs to be dealt with in a timely manner to avoid adverse effects on the serum sample.   Since there are so many problems with not flipping the serum separation gel, let's talk about what causes the serum separation gel to not flip and how to effectively solve this problem when encountering it.   The failure or poor flipping of serum separation gel may be caused by the following reasons   1. Separation adhesive formula or process reasons. The different formulas and production processes of serum separation gel can lead to different performance indicators such as thixotropy, specific gravity, and stability, thereby affecting its flipping effect.   2. The separation adhesive ages and its thixotropic performance decreases. Thixotropy refers to the ability of serum separation gel to form a colloidal isolation layer under centrifugal force. If the thixotropy is not good, the serum separation gel cannot form a stable gel like isolation layer and cannot be flipped.   3. The initial centrifugal force of the separating adhesive is too large. The serum separation gel may be damaged and unable to form a stable gel like isolation layer.   4. If the centrifugal force is too small or the centrifugal time is too short, the serum separation gel may not be able to fully flip.   5. The minimum reversal centrifugal force of the separation gel is too high, which may also cause poor or inability to reverse the serum separation gel.   6. Temperature can affect the flipping of serum separation gel. When the temperature is too high, the viscosity of the serum separation gel decreases and the fluidity increases, making it difficult to form a stable gel like isolation layer, thereby affecting its flipping effect. When the temperature is too low, the viscosity of the serum separation gel increases, the fluidity decreases, and it can also cause poor or inability to flip.   7. Humidity has a certain impact on the turnover of serum separation gel. If the environmental humidity is too high, it may cause the serum separation gel to absorb water, thereby affecting its thixotropy and stability, and thus affecting its flipping effect.   Solution for non flipping or poor flipping of serum separation gel   1. Optimize the formula of separation adhesive and strictly control the synthesis process of separation adhesive.   2. Verify and confirm that the thixotropy of the separation adhesive meets the requirements within the validity period.   3. Improve the thixotropic performance of the separation adhesive and choose a suitable supplier.   4. Operate according to the manufacturer's recommended centrifugal requirements.   5. Pay attention to controlling the ambient temperature and the temperature during centrifugation.   In summary, the use of serum separation gel requires strict adherence to operating procedures to ensure safety and effectiveness. Therefore, professional consultation should be sought before use to ensure its correct use and safety. Details can be viewed on the official website of Desheng!

Serum separation gel is a colorless or light yellow transparent colloid with good thixotropy and airtightness, and exhibits physiological inertness; Viscous fluid, whose structure contains a large number of hydrogen bonds. By utilizing its thixotropy, serum separation gel can form a gel like isolation layer between serum and blood clots, separating them, improving the recovery rate of serum, and preserving the serum in its original state. This substance is commonly used in vacuum blood collection vessels to isolate serum and blood clots.   Two methods of adding serum separation gel during use   Manual gluing method   Adding serum separation gel manually is usually done using a syringe. The specific steps are as follows:   1. Remove the needle from the front of the syringe.   2. Use a syringe to extract a certain amount of serum separation gel.   3. Drive to the bottom of the blood collection vessel.   Machine processing methods   The use of a machine for adding serum separation gel usually uses a ten channel gel adding machine, which can automatically add gel and has the function of removing bubbles, making it suitable for batch filling of serum separation gel.   The specific operation steps are as follows:   1. Place the blood collection tube that needs to be added with serum separation gel into the hopper of the machine.   2. Turn on the machine and select the corresponding program for automatic gluing.   3. The machine will automatically perform vacuum treatment to ensure that there are no bubbles inside the gel.   After adding glue, remove the test tube and perform subsequent centrifugation and other operations.   It should be noted that the machine operation needs to be set up and debugged in advance to ensure the accuracy of the gluing process. At the same time, for different brands of blood collection vessels and serum separation gel, it may be necessary to adjust the parameters or programs of the machine to ensure the correct amount and effect of gel addition.   Serum separating gel   The obvious difference between manual gluing and machine gluing   1. Operation method: Manual gluing requires manual use of tools such as syringes to add serum separation gel one by one to the blood collection vessels, which is relatively cumbersome. The machine uses automated equipment to automatically add glue in batches through preset programs and robotic arms, greatly improving operational efficiency and accuracy.   2. Glue quantity control: It is difficult to accurately control the glue quantity of each blood collection vessel by manually adding glue, which can lead to insufficient or wasted glue quantity. And machine gluing can accurately control the amount and speed of glue according to the preset program and the needs of each blood collection tube, ensuring that each tube receives an appropriate amount of serum separation glue.   3. Uniformity: Manual gluing is greatly influenced by human factors, and the operating techniques and forces of different operators may vary, resulting in less uniformity of serum separation gel in each test tube than machine gluing. The machine uses mechanical arms and other devices to achieve precise and quantitative gluing, with a uniform amount of glue in each test tube.   4. Cost: Machine gluing requires the purchase of corresponding automation equipment, and the one-time investment cost is relatively high. However, in the long run, due to the fact that machine gluing can improve efficiency and reduce labor costs, the total cost of machine gluing may be lower in large-scale and large-scale production.   5. Scope of application: Manual gluing is suitable for small-scale, low-frequency production or experimental scenarios, such as some small laboratories or research institutions. And machine gluing is more suitable for large-scale and efficient production scenarios, such as blood centers, biological product factories, and other places that require the processing of large amounts of blood samples.   In summary, manual gluing and machine gluing have their own advantages and disadvantages, and appropriate operating methods should be selected based on specific scenarios and needs. At present, the serum separation gel produced by Desheng has been widely recognized by customers in the market. For more information, please visit the official website of Desheng to learn more.

Potassium ethylenediaminetetraacetic acid has good solubility and is easily soluble in water, with a solubility of over 60% in water. At the same time, the dissolution rate of EDTA tripotassium is also fast, which makes it widely used in many fields, such as anticoagulants, ion exchangers, etc. Due to the fact that the original shape of EDTA potassium trioxide is in powder form, in order to facilitate better use by blood collection manufacturers, the raw material supplier Desheng has provided detailed operating methods.   Dissolution steps of EDTA-3K in water   1. Preparation: Electronic balance (1/10000), volumetric flask (100ml, 200ml, 500ml, 1000ml, as needed), beaker, deionized water (distilled water), glass rod, bottle washing, etc.   2. Weighing: Use an electronic balance to accurately weigh a number of pre-determined EDTA potassium powder, accurate to one percent;   3. Dissolution: This product is dissolved in distilled water and deionized water. Slowly pour EDTA potassium powder into a volumetric flask or beaker that has previously been partially filled with distilled water (deionized water) while stirring continuously. Carefully rinse the powder attached to the mouth and wall of the volumetric flask or beaker into the flask or beaker using a washing bottle; Special attention should be paid to cleaning the volumetric flask and beaker thoroughly, and there should be no impurities, oil stains, or oxides present. When using a beaker for dissolution, special attention should be paid to the control of water consumption during the dissolution process. Sufficient volume should be left for the EDTA dipotassium adhered to the cleaning glass rod, beaker, and other utensils in the future, otherwise it may cause over capacity and reduce the concentration of dipotassium.   4. Constant volume: After all EDTA potassium is dissolved, keep your eyes level with the scale line of the volumetric flask. Slowly add deionized water along the mouth wall of the volumetric flask with a washing bottle, and wait for the concave liquid level bottom to align with the scale line.   5. Mix well: Seal the mouth of the volumetric flask with a stopper, hold the upper part of the flask with one hand and press the stopper with your fingers, and hold the bottom of the flask with the other hand. Carefully invert and mix well 5-8 times.   6. Inspection and confirmation: Carefully check the key factors such as the weight weighing of potassium dioxide and the volume of the volumetric flask, recalculate the potassium dioxide content, and confirm that it is correct.   The dissolution process of EDTA tripotassium in water may cause some problems   1. Solution stability: The dissolution process of potassium ethylenediaminetetraacetate in water may affect the stability of its solution. If the dissolution rate is too fast or the temperature changes too much during the dissolution process, it may lead to precipitation or crystallization in the solution, affecting the effectiveness of use.   2. Impurities and precipitates: Potassium ethylenediaminetetraacetic acid may contain impurities or precipitates, which may precipitate during the dissolution process and affect the effectiveness of use. In addition, if unclean solvents or containers are used during the dissolution process, it may also lead to the generation of impurities and precipitation.   3. Oxidation reaction: Tripotassium ethylenediaminetetraacetic acid is a reducing substance that is easily oxidized. During the dissolution process, if exposed to oxygen or oxidized by other oxidants, it may cause changes in its chemical properties and affect its effectiveness.   4. Compatibility issues: When mixed with certain substances, potassium ethylenediaminetetraacetate may cause compatibility issues, leading to precipitation, discoloration, or gas generation in the solution. Therefore, when using potassium ethylenediaminetetraacetate, it is necessary to pay attention to its compatibility with other chemicals.   5. Environmental pollution: Failure to comply with environmental regulations or improper operation during the dissolution process may lead to environmental pollution. For example, if wastewater containing harmful substances is directly discharged into the environment, it may have adverse effects on the ecological environment.   In summary, the solubility of EDTA tripotassium is influenced by factors such as temperature, stirring speed, solvent type, and impurities. Therefore, in practical applications, adjustments and treatments need to be made according to specific circumstances.Desheng specializes in producing various types of blood collection additives.

Going to the hospital for physical examination, blood drawing is a common method of operation. Generally, analyzing the relevant values of blood samples, such as platelets, white blood cells, red blood cells, etc., can clearly determine whether the patient has any diseases. In this process, the use of anticoagulants for blood collection is crucial. As the preferred anticoagulant for medical staff, heparin lithium is generally used in blood collection to ensure that the collected blood remains in its original state before testing, in order to obtain accurate results. Let's talk about the role of heparin lithium in blood collection in detail.   What is heparin lithium?   Heparin lithium, also known as heparin lithium salt, is a form of heparin. Heparin is a naturally occurring polysaccharide, usually extracted from pig intestinal mucosa or bovine lung tissue, and can also be obtained through biosynthesis. It has a negative charge and prevents blood clotting by interacting with antithrombin III.   Principle of action of heparin lithium   Heparin lithium mainly achieves its anticoagulant effect through the following methods:   (1) Inhibition of thrombin activity: The interaction between heparin lithium and antithrombin III blocks the activity of thrombin, thereby inhibiting the coagulation process of blood.   (2) Inhibition of platelet aggregation: Heparin lithium can affect the function of platelets, reduce their adhesion and aggregation, and thus help achieve coagulation goals.   (3) Maintaining ion balance: Heparin lithium, as a salt, helps maintain ion balance in blood collection vessels, keeping the blood in its original state and unaffected by other factors.   Application of heparin lithium   Heparin lithium is mainly used in the preparation of blood collection vessels to ensure that the collected blood does not coagulate in a short period of time, which is very important for subsequent testing and analysis. The following are some main application projects of heparin lithium:   1. Clinical biochemistry examination: Heparin lithium is widely used in various clinical biochemistry examinations, such as detecting blood ammonia, electrolytes, liver function, kidney function, etc. These tests usually require original blood samples, and the use of heparin lithium ensures that blood does not clot after collection, making it easier for medical staff to complete the tests in a timely manner and obtain effective results.   2. Emergency biochemical examination: In emergency situations, it is usually necessary to quickly conduct various biochemical tests to quickly evaluate the patient's condition. The use of heparin lithium tubes can quickly process samples without waiting for long periods of time, saving patients and medical staff time.   3. Hemorheology: Hemorheology is the field of studying the flow characteristics of blood. Lithium heparin tubes are used for blood collection in some hemorheological projects to study the viscosity and fluidity of blood.   Precautions for the use of heparin lithium in blood collection   (1) Heparin lithium is different from other reagents in that it has non irreversible properties, so the test must be completed within 6 hours, as it can be affected if left for too long.   (2) Heparin lithium may be involved in the metabolism of cellular enzymes and ions, so its use level will affect the detection results, ensuring sufficient local or global anticoagulation, and ensuring the repetition of most plasma indicators.   (3) Due to the spraying of heparin lithium on the tube wall, in order to ensure ideal anticoagulation effect, it is recommended to immediately mix it up and down 5-8 times after blood collection.   Heparin lithium is an important component in the preparation of blood vessels, playing a crucial role in clinical and emergency biochemical examinations. By preventing blood clotting, heparin lithium ensures the quality and reliability of collected blood samples, helping medical staff better evaluate the patient's health status and develop corresponding treatment plans.   As a professional manufacturer of heparin lithium, Desheng can provide raw materials and reagents with high main content and analytical purity for convenient configuration and use by blood collection manufacturers. At present, we have established contact with multiple domestic enterprises and have long-term stable supply.

Heparin lithium is a common anticoagulant, and as a form of heparin, it plays an anticoagulant role in blood testing. Compared to heparin sodium, heparin lithium is often more popular because it has less impact on water molecules and can reduce interference with blood components. During the process of blood collection and analysis, the integrity of the blood is maintained to ensure accurate test results. It is precisely because of this characteristic that it is widely used in various biochemical tests. Let's take a specific look at what test tubes with added heparin lithium can be used to detect?   1、 Liver function examination   The liver is one of the most important organs in the human body, covering various biochemical processes. Therefore, checking liver function is very important for diagnosing and preventing diseases, such as cirrhosis, fatty liver, viral hepatitis, liver cancer, liver abscess, etc. The application of heparin lithium in liver function testing can inhibit blood coagulation, keep the blood in its original state, ensure sample stability, and thus ensure accurate measurement of various biochemical indicators.   2、 Hemorheology   Hemorheology studies the flow characteristics of blood within blood vessels, which is helpful for the diagnosis and treatment of cardiovascular diseases, anemia, and other diseases. In certain disease states, such as cardiovascular and cerebrovascular diseases, the patient's blood viscosity may undergo abnormal changes. At this time, the application of heparin lithium can effectively prevent blood clotting, ensure the integrity of the blood during testing, and provide more accurate rheological values.   3、 Special testing items   Heparin lithium is also suitable for some special testing items, such as arterial blood gas analysis, electrolyte, calcium ion determination, etc. These items usually require the use of anticoagulants to ensure the stability of blood samples. Heparin lithium not only effectively inhibits coagulation, but also does not interfere with the determination of specific items mentioned above, ensuring the reliability of the test results.   4、 Biochemical examination after hemodialysis   Hemodialysis is a treatment method used to replace the kidneys in removing waste and excess substances. However, during the dialysis process, patients' blood may not be easily separated from serum samples after using anticoagulants, leading to difficulties in biochemical testing. The use of test tubes containing heparin lithium not only has no effect on sample blood cells, but also allows for more accurate test data.   Heparin lithium, as an anticoagulant widely used in biochemical testing, not only ensures the stability of experimental blood samples, but also helps medical staff and patients save diagnostic time. As a favored reagent, its raw material quality requirements are very high. As a manufacturer, Desheng has supplied hundreds of blood collection enterprises with high main content, no impurities, and stable use.

Electrolytes are ions in the body, including chloride ions, potassium ions, sodium ions, etc. They play a crucial role in regulating intracellular and extracellular osmotic pressure and maintaining normal physiological functions. Once someone is taken to the hospital due to summer heat stroke, doctors will recommend that the patient undergo an electrolyte test to ensure that the electrolyte content in the body is within the normal range, which is a key means of evaluating the patient's overall health and whether there is electrolyte disorder.   1、 The importance of electrolyte testing   The importance of electrolyte testing lies in its ability to reveal whether the body's electrolytes are in a balanced state. Only when the electrolyte concentration is maintained within a normal range can the body's metabolic process proceed smoothly. When electrolyte disorders occur, patients may experience severe symptoms such as poisoning, convulsions, and coma. Therefore, electrolyte testing is a guarantee for early diagnosis and treatment of patients.   2、 Electrolyte detection and blood sampling additives   When conducting electrolyte testing, selecting an appropriate test tube for blood collection is crucial. Generally, substances such as anticoagulants, coagulants, or separators are added to the blood collection tube, and the items applicable to different test tubes with these additives also vary. However, electrolyte tubes typically contain heparin lithium anticoagulants, which can prevent blood clotting and ensure the stability of the blood sample.   3、 The anticoagulant mechanism of heparin lithium   Early electrolyte testing may use heparin sodium as an anticoagulant, but with the development of technology, heparin lithium has replaced the application of heparin sodium in this field. The reason for this change is the advantage of heparin lithium in anticoagulation. It can inactivate thrombin by activating antithrombin III, without interfering with electrolyte measurements such as potassium ions, sodium ions, and chloride ions, thus ensuring the accuracy of experimental results. In addition, heparin lithium can also prevent platelet aggregation, further enhancing its anticoagulant effect, making it an ideal anticoagulant for electrolyte detection.   In electrolyte testing, selecting the appropriate test tube is crucial. As an excellent anticoagulant, heparin lithium has significant advantages in electrolyte testing. It not only helps medical staff improve efficiency, but also ensures patient testing results, enabling them to receive timely treatment.   As a raw material supplier for blood vessel additives, Desheng can provide a full range of reagents, such as serum separation gel, heparin lithium, heparin sodium, EDTA potassium salt, etc., all of which are of analytical purity grade, with high main content, no odor or impurities, making it easy to prepare, store, and transport.

Biobuffering agent HEPES is a pH regulator commonly used in biochemical and cellular biology research. Although there are various types of biological buffering agents and HEPES is not irreplaceable, HEPES buffer is a zwitterionic buffering agent containing amino and carboxyl groups, with stable pH performance. So it is widely used in biochemical and cellular biology experiments that require precise control of pH.   Characteristics of HEPES   The molecular weight of HEPES is 247.32, and its molecular structure is stable. The pH buffer range is 6.8 to 8.2, showing neutrality and good thermal stability at room temperature. Due to its non ionic properties, it can still maintain high solubility in high ionic strength solutions.   Application Fields of HEPES   1. HEPES is commonly used in biochemical research to prepare enzyme reaction mixtures. In the presence of high concentrations of electrolytes, HEPES can also serve as an effective ion carrier. HEPES is often used as a buffer for cell culture media in cell culture;   2. HEPES is used as a pH regulator and moisturizer in the field of daily chemicals, commonly used in skincare products and shampoo, while maintaining the stability of product ingredients.   Although HEPES has a wide range of uses, it also has its limitations. In high concentration salt solutions or certain organic solvents, the buffering capacity of HEPES will decrease. In order not to affect the experimental results, please choose a biological buffer that meets the experimental requirements as appropriate to ensure the orderly progress of the experiment.   Preparation method of HEPES buffer solution   Taking the configuration of a HEPES solution with a pH of 7500 milliliters as an example:   1. 119g of HEPES powder, 500ml of deionized water, 0.5-1M sodium hydroxide solution, stirring rod, and large beaker need to be prepared;   2. Add 400ml of deionized water to 119g of HEPES and stir until dissolved;   3. Slowly add 0.5-1M sodium hydroxide and adjust to the required pH value of 7;   4. Add the remaining 100 milliliters of deionized water to a constant volume of 500ml;   Precautions for using HEPES   When preparing or using HEPES buffer, the following points need to be noted:   1. Avoid contact between HEPES and metals to prevent metal ions from reacting with the components in the buffer solution, which may affect the buffering effect;   2. Due to the potential toxicity of HEPES to cells at high concentrations, the concentration should be controlled during use and combined with the use of sodium carbonate to counteract changes in osmotic pressure;   3. When preparing HEPES solution, please wear protective masks and gloves, as contact between the reagent and the skin may cause discomfort;   4. The prepared buffer should be stored away from light to maintain its chemical stability.   The above listed mixing methods are relatively conventional and for reference only. When using them, flexible mixing should be carried out according to experimental requirements.   In summary, HEPES buffer has a wide range of uses, which can maintain pH stability in the experimental environment and protect the activity of biological samples from being affected. Understanding the characteristics, uses, and preparation methods of HEPES buffer is of great significance for biomedical researchers, as it can make their experiments smoother.   Hubei Xindesheng Material Technology Co., Ltd. is a professional manufacturer of biological buffering agents.
