Heparin is a commonly used anticoagulant in clinical practice, widely used in blood tests and various medical procedures. Generally, it has two salt forms, namely sodium heparin and lithium heparin, both of which play an anticoagulant role. However, although their effects are similar, their binding ions and degree of dissociation are different. Heparin lithium exhibits better anticoagulant effects than heparin sodium in certain situations and is more suitable for certain blood test items. Let's take a look at the blood test items suitable for heparin lithium.   1、 Biochemical testing of patients after hemodialysis   For biochemical tests of hemodialysis patients, heparin lithium plays a significant role. For example, during hemodialysis, the dialysate usually contains heparin anticoagulants, such as low molecular weight heparin calcium. These anticoagulants can make blood samples less prone to clotting, making it difficult to separate samples and obtain plasma. Therefore, using heparin lithium anticoagulant plasma is an ideal choice for biochemical testing in dialysis patients. It not only effectively prevents blood clotting, but also helps to extract accurate plasma samples. According to reports, the accuracy of the results is high.   2、 Liver function examination   Blood samples treated with lithium heparin also have a special role in liver function tests, which usually involve the analysis of multiple blood parameters to evaluate liver health, effectively treat or prevent diseases. The use of heparin lithium tubes for examination, such as in the detection of liver diseases such as hepatitis, liver cancer, and fatty liver, helps to maintain blood flow, make the measurement of various blood parameters more accurate, and thus improve the efficiency of the examination work.   3、 Hemorheological testing   In the detection of cardiovascular and cerebrovascular diseases, the rheological properties of blood are very important. Some diseases, such as high viscosity, lead to abnormal increases in blood viscosity, which may increase the risk of thrombosis and cardiovascular disease. In these cases, hemorheological testing can help identify risk factors. Heparin lithium, as an anticoagulant, can be used to ensure that blood maintains fluidity during rheological testing, without causing inaccurate results due to coagulation, which is helpful for early diagnosis of cardiovascular and cerebrovascular diseases.   Lithium heparin is widely used in blood tests, and its superior anticoagulant performance makes it an ideal choice for medical staff. As a manufacturer of lithium heparin raw materials, Desheng can supply high-quality reagents of analytical grade. More than 100 domestic blood collection manufacturers have chosen to cooperate with us. If you have any relevant intentions, please feel free to contact us for purchase at any time!

In the modern medical field, the collection and analysis of blood samples are very common clinical operations, and blood testing is one of the important ways for doctors to diagnose and monitor the health status of patients. To ensure that the collected blood samples do not coagulate after collection and to ensure accurate experimental results, appropriate anticoagulants need to be used. And the heparin lithium collection tube is one of them, and its working principle and application will be introduced below.   1、 The working principle of heparin lithium   Heparin lithium is an anticoagulant reagent, usually prepared as a solution from powder and sprayed onto the inner wall of blood collection vessels. Its main function is to prevent blood from clotting after collection, ensuring that the blood sample remains in its original state for subsequent testing. The anticoagulant mechanism is mainly due to the fact that heparin lithium can bind with antithrombin III (AT-III) to form the heparin AT-III complex. AT-III is a naturally occurring protease inhibitor that can reduce the activity of coagulation factors such as Xa and IIa. By binding to AT-III, coagulation factors are inactivated, thereby inhibiting the formation of prothrombin kinase and further preventing blood clotting.   2、 Application of heparin lithium collection tube   Lithium heparin collection tubes have a wide range of applications in medical laboratories and clinical practice. Firstly, it is commonly used in biochemical tests to evaluate liver function, kidney function, glucose metabolism, lipid metabolism, etc. It can ensure that blood samples remain stable after collection, thereby providing reliable detection results. In addition, in coagulation tests, it is necessary to analyze coagulation factors in the plasma, such as PT (prothrombin time) and APTT (activated partial coagulation time). The heparin lithium collection tube can ensure the stability of the plasma and is suitable for these tests.   3、 Precautions for using heparin lithium collection tubes   To ensure sufficient anticoagulation of the blood in the collection tube, the blood sample should be reversed and mixed 5-8 times as soon as possible after collection, especially when the blood collection environment is above 25 degrees Celsius. Effective contact between the blood and heparin lithium must be ensured, otherwise local coagulation and non coagulation may occur, which is not conducive to subsequent testing. In addition, as heparin anticoagulation is not irreversible, the collection tube should be tested within 6 hours after blood collection and should not be left idle for a long time, which may cause accidents.   Overall, the use of heparin lithium collection tubes in medical laboratories ensures the accuracy and reliability of blood samples, helping medical staff to make accurate diagnoses and treatments. This anticoagulant is also recognized as an ideal anticoagulant in the medical field. Note that when using heparin lithium collection tubes, it is necessary to follow standard blood collection procedures and operating procedures to ensure the quality of the collected samples.   As a supplier of blood vessel additives, Desheng can provide high-quality raw material powders and has the ability to provide long-term supply and improve after-sales service. It has high market recognition and many repeat customers. If you are interested, please feel free to contact us for purchase at any time!

The collection and processing of blood samples are crucial in clinical laboratory examinations. Among them, procoagulant blood collection is often used for coagulation tests and early diagnostic experiments for some diseases. However, hemolysis may occur when using blood collection vessels containing coagulants. Hemolysis is a complex process that can affect the accuracy and reliability of experimental results. This article will explore the reasons for hemolysis in blood collection using coagulants.   The components and effects of coagulants in blood collection   Coagulant agents usually contain coagulant powder (a white powder substance that needs to be prepared as a solution when used) or coagulant suspension (a milky white suspension that can be directly sprayed for use) in blood collection. The function of these two reagents is to accelerate the coagulation process of blood, causing it to quickly form clots in the blood collection vessel. This component has no effect on clinical biochemical testing and can facilitate subsequent experimental analysis.   The causes of hemolysis phenomenon   Hemolysis refers to the process in which red blood cells rupture and release intracellular substances during the preparation process after blood samples are collected from blood collection vessels. This may affect the experimental results, especially for experiments that require detection of intracellular components in red blood cells. There are various reasons for hemolysis during the use of coagulant blood collection vessels. Below, we will explore in detail some of the main reasons.   1. Improper blood collection   During the blood collection process, if the operation is improper or the blood collection technique is not proficient, it may cause damage to the blood vessel wall, leading to hemolysis. In addition, excessive compression or forceful shaking of the blood collection tube may also cause red blood cell rupture.   2. The stimulating effect of coagulants   Some coagulants may have a stimulating effect on red blood cells, leading to their rupture. When choosing products, it is important to purchase from reputable manufacturers or channels. Ensure reliable product quality.   3. Transportation and storage conditions   Improper transportation and storage conditions may cause shaking or temperature changes in the blood collection vessel, leading to hemolysis. For example, long-distance transportation or extreme temperature environments may cause the components inside the blood collection vessel to separate or produce bubbles, leading to the rupture of red blood cells.   4. Improper specimen handling   During specimen processing, if the mixing time is too long and the force is too strong, it may damage red blood cells and cause hemolysis. In addition, if the blood collection tube is not evenly filled and applied before use, it may also lead to some blood samples not fully contacting the coagulant, forming clots, while other parts continue to undergo hemolysis.   Strategies and methods to reduce hemolysis   In response to the possible causes of hemolysis mentioned above, the following strategies and methods are provided to reduce the occurrence of hemolysis:   1. Improve blood collection techniques   Strengthen training and technical guidance for blood collection personnel to enable them to master correct blood collection techniques and methods.

This chelation can effectively prevent metal ions from precipitating in the solution, thereby stabilizing the solution.   2、 Application of EDTA disodium in vacuum blood collection   In medical experiments, vacuum blood collection vessels are used to collect blood samples from patients for various medical tests. During this process, EDTA disodium was used as an anticoagulant. Its working principle is to chelate with calcium ions in the blood, preventing calcium ions from participating in the blood coagulation process, thereby playing an anticoagulant role. Meanwhile, EDTA disodium can also protect platelets in the blood and improve the quality of blood samples. In addition to EDTA disodium, commonly used anticoagulants include EDTA dipotassium and EDTA tripotassium. Generally, the selection of usage will be based on specific testing items.   3、 Application of EDTA Disodium in Cosmetics   In the field of cosmetics, EDTA disodium is mainly used as a chelating agent and antioxidant. As a chelating agent, it can avoid the interference of metal ions on the active ingredients in cosmetics and improve the stability of the product. At the same time, it can also chelate heavy metal ions in cosmetics, such as lead and mercury, to prevent their damage to the skin. As an antioxidant, it can protect the oils and vitamins in cosmetics from oxidation, thereby extending the shelf life of the product.   4、 The Safety of EDTA Disodium   Although EDTA disodium has wide applications in many fields, its safety still needs attention. Studies have shown that excessive use of cosmetics containing disodium EDTA may cause some adverse reactions. Excessive addition of EDTA solution to blood collection vessels can lead to deviation in blood test sample results. Therefore, whether using vacuum blood collection or as a cosmetic ingredient, it is necessary to strictly follow the ratio and relevant regulations for operation to ensure safe and effective use.   It is worth noting that although EDTA disodium is used in vacuum blood collection and cosmetics, the quality, grade, and product price are completely different.

Among them, HEPES buffer, as a compound with excellent performance, has been widely used in the field of cosmetics.   HEPES is a compound with excellent properties, chemically named 4-hydroxyethylpiperazine ethanesulfonic acid, suitable for formulation in sensitive skin and periocular products. Meanwhile, HEPES is not easily decomposed at high temperatures and has good chemical stability, which can meet the stability requirements of cosmetics during storage and use. Moreover, HEPES has good permeability and moisturizing properties, which can promote the absorption of nutrients by the skin and improve skincare effectiveness. This article will provide a detailed introduction to the application of HEPES in cosmetics and the advantages of Desheng HEPES.   The application of HEPES in cosmetics   1. Facial cleansing products: Adding an appropriate amount of HEPES to facial cleansing products can reduce their irritation, while improving their cleaning power and moisturizing effect. This helps alleviate the dryness and tightness of the skin during the cleaning process.   2. facial mask: Adding proper amount of HEPES into facial mask can improve the moisturizing and permeability of facial mask, so that facial mask can quickly play its role in a short time to achieve better skin care effect. At the same time, HEPES can also promote the fit between the facial mask and the skin, so that the facial mask can form a protective film on the skin, reducing the stimulation of the external environment on the skin.   3. essence liquid: essence liquid is a high concentration skin care product, which usually contains a large number of active ingredients. Adding an appropriate amount of HEPES to these products can improve their stability and permeability, allowing the active ingredients to be better absorbed and utilized by the skin. In addition, HEPES can also improve the moisturizing degree of skin and reduce the skin dryness caused by the use of essence.   4. Sunscreen: Sunscreen is an important product that protects the skin from UV damage. Adding an appropriate amount of HEPES to sunscreen can improve its moisturizing and stability, forming a protective film on the skin and better resisting UV damage. Meanwhile, HEPES can also alleviate skin dryness and tightness caused by the use of sunscreen.   5. Shampoo, shower gel and other shampoo and care products: Adding an appropriate amount of HEPES to shampoo, shower gel and other shampoo and care products can reduce their irritation, improve their cleaning and moisturizing effects. This helps to protect the health of the scalp and skin, alleviate the dryness and tightness caused by the use of these products.   Advantages of Desheng HEPES   1.

The quality of serum separation gel is affected by the production raw materials. The type, quality, purity, and ratio of raw materials used in production will have an impact on the performance and quality of serum separation gel.   Common raw materials for producing serum separation gels include hydrophobic organic compounds and silica powder. These raw materials are combined to form a gel like liquid with good thixotropy, which contains a large number of hydrogen bonds in its structure, forming a network structure.   With the development of medical technology, the demand for serum separation gel is increasing, and its use in fields such as beauty medicine is also becoming more and more widespread. Therefore, some serum separation gel manufacturers have started using hydrophobic resin materials to make the performance of serum separation gel more eye-catching in various aspects, and the appearance can be changed according to customer requirements.   At present, the commonly seen serum separation gel on the market is produced by Desheng, which is mainly divided into two materials: resin and acrylic ester.   The main component of acrylic separation adhesive is polyacrylate. After the improvement of the previous generation, this separation adhesive is a hydrophobic material that does not absorb water and fuse. Its flipping performance and thixotropy have been improved, and it is highly popular in the market.   The advantages of acrylic separation adhesive mainly include:   Rapid curing: Acrylic separation adhesive has the characteristic of rapid curing, which usually only takes a few seconds to minutes to reach the initial curing state, improving production efficiency.   Good weather resistance: Acrylic separation adhesive maintains stable performance in indoor and outdoor environments for a long time.   Good chemical resistance: Acrylic separation adhesive has good resistance to some chemical substances and can resist the erosion of acids, bases, solvents, etc. to a certain extent.   High transparency: Acrylic separation adhesive has high transparency and is suitable for application scenarios that require maintaining the transparency of the material surface.   The disadvantages of acrylic separation adhesive mainly include:   Slow reaction speed: Common two-component epoxides often require several hours to reach their intended strength, and require high mixing ratios. Single component epoxy often requires heating in order to rupture the encapsulated curing agent inside, making operation inconvenient.   Single component epoxy may have capillary effects: on construction surfaces with small gaps, due to the large diameter of the curing agent particles, they cannot penetrate into the gaps, resulting in uneven distribution of some adhesive components and the inability to cure.   The main component of resin separation adhesive is straight chain alkane resin. This separation gel has been further improved, with better physiological inertness, less aging, and radiation resistance. Even after sterilization treatment in test tubes, it will not have any impact.   1. Strong selectivity: Resin separation technology can select suitable resins based on the properties of the target substance, achieving efficient and selective adsorption of the target substance.   2. Easy to operate: The resin separation technology is easy to operate and does not require complex equipment or operating steps, making it easy to master.   3. Wide application: Resin separation technology is suitable for the separation and purification of various types of substances, and has a wide range of application areas.   The disadvantages of resin separation adhesive mainly include:   Raw material source limitation: The raw material source for resin separation adhesive may be limited, and not all resins can be used for the preparation of separation adhesive.   Separation effect limitation: The separation effect of resin separation adhesive may be affected by some factors, such as the properties of the target substance, separation conditions, etc.   High cost: The preparation cost of resin separation adhesive is high and may not be suitable for large-scale application. In summary, the quality of separation gels made from different raw materials will vary. Use according to different scenarios. Desheng specializes in producing blood vessel additives.
