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.

Heparin lithium, as an anticoagulant, plays an important role in clinical biochemical tests. Its main function is to prevent coagulation during the collection of blood samples, ensuring their stability and reliability. The principle of action is achieved by blocking the activity of thrombin, an enzyme that promotes blood clotting. Heparin lithium inhibits thrombin activity by binding to antithrombin III, thereby reducing blood clotting. What is its clinical function? Let's take a look together.   The biggest function of heparin lithium is in the collection of blood samples and anticoagulation during clinical biochemical examinations, especially for testing items that require the determination of ion content in the blood. Compared with other anticoagulants, heparin lithium has less interference in ion determination, enabling accurate and reliable results to be obtained during blood sample collection and ion content determination. Moreover, heparin lithium has an advantage that it can be used at room temperature and added to the blood collection vessel as a solution without special conditions. In addition, its anticoagulant performance ensures that the blood sample is not damaged and subsequent testing is smoother.   However, it should be noted that although heparin lithium is an effective anticoagulant, it is not a drug and cannot be used as an injection, nor should it be directly injected into human or animal bodies. The use of heparin lithium additive is limited to the process of collecting blood samples in the laboratory, with the aim of maintaining the original state of the blood samples and ensuring the accuracy of various biochemical tests.   In addition, in order to ensure the ideal anticoagulation effect of blood samples, test tubes containing heparin lithium should be immediately inverted after blood collection, especially when the ambient temperature is above 25 degrees Celsius, which is not well mixed and easily leads to a semi coagulation state and is not suitable for biochemical testing. And unlike other additives, heparin lithium must be tested within 6 hours and should not be left unused for too long. For sensitive indicators such as AST, ALT, TBIL, DBIL, GGT, etc., it should be ensured that most of the plasma indicators are repeatable within 6 hours.   Unlike heparin drugs, heparin lithium additives cannot be used for treatment or directly injected into human or animal bodies. If you need to use it, you should indicate the demand in advance.As a professional manufacturer of blood vessel additives, Desheng can provide analytical grade heparin lithium raw materials for blood collection manufacturers to use, and does not participate in human treatment. Before purchasing, please explain the purpose in advance to facilitate accurate customer service quotations. Interested parties are welcome to click on the website to inquire about details!

In laboratory and clinical medicine, anticoagulants are a common reagent that can be used to prevent blood clotting and ensure the stability of blood and biological samples, which is crucial for various tests and biochemical analysis. The two common anticoagulants among them are heparin lithium and EDTA (ethylene diamine tetraacetic acid). Although they are both added to test tubes as in vitro anticoagulants, their principles of action and applicable items differ greatly. Below, we will delve into the properties, application fields, and importance of these two anticoagulants in laboratory work.   Heparin lithium   Heparin lithium is a sulfur-containing polysaccharide with negative charges. Its main mechanism is to activate antithrombin III, prevent the activation of thrombin, and slow down the coagulation process. It is used in blood collection to prevent blood from clotting inside the tube, which maintains the fluidity of the blood sample for various clinical tests, such as hemodialysis and liver and kidney function testing. However, it should be noted that although heparin lithium performs well in anticoagulation, it can also interfere with certain experiments, such as thrombin time (PT), activated partial coagulation time (APTT), and international standardized ratio (INR) in coagulation tests. Therefore, when conducting such tests, it may be necessary to consider using other anticoagulants.   EDTA (ethylene diamine tetraacetic acid)   EDTA is a strong chelating agent that can form stable complexes with calcium and other multivalent metal ions. This characteristic makes it a superior anticoagulant and can exist in the form of EDTA dipotassium or tripotassium in clinical practice. In blood samples, EDTA is usually combined with calcium ions in the blood to prevent blood clotting, and is usually suitable for whole blood cell counting or blood biochemical analysis.   Precautions for the use of heparin lithium and EDTA   1. To ensure sufficient anticoagulation of blood, both heparin lithium tube and EDTA tube should be inverted and mixed 5-8 times immediately after blood collection, and it is important not to shake excessively to cause blood cell rupture.   2. Both heparin and EDTA tubes are non irreversible anticoagulants, and the experiment should be completed within a short period of time. Typically, heparin tubes are completed within 6 hours, while EDTA tubes are completed within 24 hours. Remember not to leave them for too long, as it may lead to abnormal results.   3. Note that there are differences in the dosage of the two types of tubes. According to industry standards, the dosage range for heparin lithium tubes is 9.4IU-28IU per milliliter of blood sample, while the standard dosage for EDTA potassium is 1.5-2.2mg per milliliter of blood.   Both heparin lithium and EDTA are important anticoagulants in clinical practice. When choosing anticoagulants, it is necessary to weigh them based on specific applications, experimental types, and possible interference factors. Correct selection and use are beneficial to ensure that experimental results do not deviate. As a manufacturer of heparin lithium, Desheng provides raw material powder of analytical purity level, without impurity interference, and is easy to preserve and prepare. It can be added in batches to blood collection vessels to improve efficiency. If you have any interest, please feel free to click on the website and contact us anytime to purchase!

Lithium heparin is a form of heparin, which appears as a white powder and is stable at room temperature. It has good water solubility and can be easily prepared into blood vessels. Due to its ideal anticoagulant effect, it is often applied in the medical field, suitable for detecting indicators such as blood sugar and liver and kidney function. Medical staff provide timely assistance to patients by analyzing sample data. So what exactly does it have on the blood? Let's take a look together.   Anticoagulant mechanism   The main function of heparin lithium is to prevent blood clotting by inhibiting the activity of thrombin. Thrombin is an enzyme that plays a crucial role in the blood coagulation process. Heparin lithium enhances the inhibitory effect of antithrombin III on thrombin by binding to it, thereby reducing its activity and slowing down the coagulation process, making blood less prone to clotting, thereby improving the efficiency of blood sample processing.   Application of heparin lithium in blood collection   Heparin lithium plays an important role in the preparation of blood vessels, as most biochemical tests require the blood to be in an uncoagulated state. In this case, it can serve as an anticoagulant to assist. It has the following characteristics in blood collection:   (1) Prevention of coagulation: Its main function is to inhibit thrombin, thereby avoiding blood coagulation during the blood collection process, ensuring that the collected whole blood sample remains in its original state before testing.   (2) High content: Usually, heparin lithium is in its original factory state as powder, and the raw materials prepared into the blood collection vessel are generally of high analytical purity, ensuring that it does not introduce any impurities or interfering factors and does not affect the accuracy of the test results.   (3) Stability: Heparin lithium is a stable anticoagulant that does not decompose or lose anticoagulant properties when added to test tubes at room temperature, which is beneficial for storing test tubes.   Heparin lithium, as an important anticoagulant, is widely used in the medical field. It prevents blood clotting by inhibiting the activity of thrombin, ensuring that collected blood samples remain in their original state for various tests. The premise for these effects is the quality of heparin lithium, and the choice of its source manufacturer is particularly important.   Here, we recommend that you choose Hubei Xindesheng, which can provide a full range of blood collection additives, all of which are analytical grade. It is a cooperative partner of most domestic blood collection manufacturers, and due to independent production and research and development, it is sold in stock, without shortage or shortage, with favorable prices. If there are any problems, after-sales service will solve them as soon as possible to ensure that customers can use them with confidence.

A dark green lithium heparin tube is commonly used for collecting and preserving blood samples, as it contains lithium heparin as a blood anticoagulant used to inactivate certain coagulation factors in the blood. In general, in medical practice, heparin lithium tubes play an important role in specific tests and tests, which are used to check blood ammonia levels and rheological parameters of the blood.   Applicability of heparin lithium tube:   1、 Check blood ammonia levels   Blood ammonia level refers to the concentration of ammonia nitrogen in the blood, usually expressed in mmol/L (millimoles/liter). Ammonia nitrogen is a form of ammonia, a compound of ammonia oxides, produced by the metabolism of amino acids in the liver. The liver is the only organ capable of relieving ammonia toxicity, so blood ammonia levels are crucial for evaluating liver function. Abnormal blood ammonia levels may indicate severe liver damage, such as liver diseases such as hepatitis and cirrhosis, or upper gastrointestinal bleeding, where blood breakdown increases ammonia nitrogen levels. By measuring blood ammonia levels, doctors can evaluate liver function and the patient's metabolic status.   2、 Hemorheological testing   Hemorheological testing is a testing method used to evaluate blood flow and viscosity. It mainly includes two parameters: whole blood viscosity and plasma viscosity. The former refers to the viscosity of the entire blood sample, and abnormal whole blood viscosity can be seen in various diseases, such as cardiovascular and cerebrovascular diseases, hypertension, coronary heart disease, as well as malignant tumors, anemia, etc. The latter refers to the viscosity of the plasma. Abnormal plasma viscosity can be seen in multiple myeloma, diabetes, etc. Hemorheological testing helps to understand the characteristics of blood, identify factors that may cause abnormalities, such as viscous blood that may increase the risk of cardiovascular and cerebrovascular diseases, and help doctors develop more accurate treatment plans.   These testing items require unconsolidated and stable blood samples, and the blood has been processed using heparin lithium tubes, which have no interference with blood components and are conducive to the smooth and effective completion of the above experiments, thus obtaining reliable results and timely treatment and prevention of related diseases for patients.   As a manufacturer of blood vessel additives, Desheng has a wide range of reagent product types and can provide customers with diversified choices. At the same time, due to its direct sales by the manufacturer, there is no secondary intermediary to make a difference in price, with favorable prices and stable supply.

Heparin lithium, as an anticoagulant, has a wide range of applications. Due to its natural anticoagulant properties, it plays an important role in blood sample collection and anticoagulation processes in clinical biochemical and emergency biochemical examinations. Since it is used as an anticoagulant reagent, it must also be very useful in the medical field. Let's take a specific look together.   1、 Clinical Biochemical Examination   Clinical biochemical tests include common blood tests, such as detecting ion content, liver function, kidney function, and blood lipid levels in the blood. The function of heparin lithium as an anticoagulant is to prevent premature coagulation of blood after collection, thereby ensuring the stability of blood samples. In these tests, accurate results are a prerequisite for disease diagnosis and treatment.   2、 Hemorheology project   Heparin lithium is not only used for general biochemical tests, but also widely used in hemorheology projects. Hemorheology mainly studies the flow properties of blood in blood vessels, which involves key indicators such as blood viscosity and cohesion. The addition of heparin lithium in these items can effectively prevent blood clotting and ensure measurement accuracy.   3、 Determination of blood ion content   In clinical testing, measuring the ion content in the blood is a common operation, such as measuring the concentration of calcium, potassium, and sodium plasma. Heparin lithium is recommended as an anticoagulant mainly because it has minimal interference with the determination of other ion concentrations, ensuring the accuracy of ion concentration measurement and providing important information for the diagnosis and treatment of various diseases.   4、 Fast and stable   Heparin lithium quickly plays a role in blood sample collection, ensuring that the blood does not coagulate after collection, maintaining a stable state of the sample before further testing. This is particularly important for medical staff, especially in emergency biochemical tests where time is crucial.   5、 Precautions for use   Although heparin lithium has extensive applications in multiple fields, some precautions need to be followed when using it. Firstly, heparin lithium is not a drug and cannot be used as an injection. Direct injection into humans and animals is prohibited. Secondly, the anticoagulant effect of heparin lithium is reversible, so the collection and testing of blood samples need to be completed within the specified time, usually within 6 hours. Outdated samples may lead to errors in the test results.   The quality of heparin lithium raw material is crucial when used in blood collection. Unqualified heparin lithium may affect the results of later testing. Therefore, everyone should pay attention to choosing reliable suppliers and manufacturers to obtain high-quality heparin lithium. Here we recommend Hubei Xindesheng, which can supply raw material powder with high main content and low impurities, for use by blood collection manufacturers. After repeated testing, it has high stability. If you have any interest, please feel free to contact us for purchase!

Heparin sodium and heparin lithium are two common anticoagulants that play important roles in clinical and laboratory applications. Although they are very similar in terms of names and the raw materials are in powder form, they are prepared into solutions and added to test tubes for use, but there are significant differences in chemical properties and some specific applications. Let's take a look together.   Different chemical properties   1. Different nuclear charge numbers: One of the biggest differences between heparin sodium and heparin lithium is that they contain different metal ions. Sodium heparin contains sodium ions (Na+), while lithium heparin contains lithium ions (Li+). Lithium ions have a lower nuclear charge than sodium, making them more chemically stable.   2. Differences in coagulation speed: Due to the different nuclear charge numbers between heparin lithium and heparin sodium, the interaction speed between heparin lithium and platelets (PLT) is slow. In contrast, the binding speed between heparin sodium and PLT is relatively fast, which may be unfavorable for certain laboratory applications. For example, heparin sodium is not suitable for whole blood cell analysis, as the faster aggregation speed of PLT may lead to inaccurate results.   Differences in binding mechanisms   Both heparin sodium and heparin lithium are different forms of heparin, but their binding mechanisms differ. Heparin lithium can be understood as being replaced from heparin sodium, so their effective binding ions are different.   The recommended dosage is different   In the industry standards for vacuum blood collection, there are different dosage ranges for heparin sodium and heparin lithium. Normally, there is 12-30IU of heparin sodium per milliliter of blood, but the recommended dosage range for heparin lithium is usually between 9.4IU-28IU per milliliter of blood. This difference needs to be considered in the laboratory and blood collection process to ensure the correct anticoagulant effect.   From the above, there are significant differences between heparin sodium and heparin lithium, especially in terms of chemical properties, binding mechanisms, and anticoagulant dosage. When using, attention should be paid to selecting test tubes that meet experimental requirements for blood collection or experimentation to ensure safety and effectiveness.
