what is serum separator gel made of       As a chemically inert polymer, the serum separation gel exists in the form of a viscous colloid, with a key specific gravity between 1.045-1.065g/cm3, just between the serum and the blood clot. Then, through centrifugation, it can be flipped to the center of the blood collection vessel, completely separating the serum and blood clots, thereby quickly and efficiently extracting the serum sample. However, there are many types of separated gel on the market, and the composition and production of each type are different. What is it made of? Below is a detailed introduction for everyone.       1、 Polysiloxane separation gel       This type of separation gel is mainly made of SiO ₂, polysiloxane, diluent and other additives. Among them, polysiloxane is the key, occupying a content between 80% -90%, with SiO2 added at around 10% -15%, and diluents and other additives at around 2%. Although this kind of separation gel is sold on the market, hemolysis often occurs in experiments due to unstable performance, and there are not many users in general.   Serum separating gel       2、 Acrylate separation gel       It is mainly made of fumed silica, polyacrylate, and additives, with polyacrylate as the main content, accounting for about 96%, fumed silica is about 3%, and other additives are about 1%. Compared with the preparation of the first separation gel, the performance of this acrylic acid separation gel has been further improved. Because it contains acrylate, it will not appear water absorption and swelling, and has good wire drawing property. This is a separation gel that is widely used in the market, and also a product widely selected by the public.       3、 Resin separation gel       This is a new generation of research and development product, mainly made of straight chain alkane resin. Compared with the first two, it has stronger physiological inertness, not only resistance to hydrolysis and irradiation, but also improved reagent compatibility. Since the raw material price of straight chain alkane resin is high and the production cost is high, the price is slightly more expensive than other types of separation gel, which is generally suitable for high specification blood collection experiments, such as PRP tubes in the medical and aesthetic field.       The types of serum separation gel are different, and their manufacture is also different. When using, we must choose products with high cost performance and reliable quality according to the experimental requirements. As a manufacturer specializing in the production of serum separation gel, Desheng Biochemical has developed in China for 18 years. It is equipped with a senior research and development team. The separation gel has high production efficiency and sufficient stock. Because it is delivered directly by the manufacturer, the price is favorable.

serum separator gel composition       In clinical blood detection, blood collection vessel is a container widely used for blood sample collection. Because of its internal separation gel composition that can accommodate and separate serum and plasma, it is the preferred product of major medical institutions. In addition, because of the special gravity of serum separation gel, it can not only effectively separate serum and plasma, but also complete the preservation and transportation of blood samples to prevent secondary infection accidents of blood samples. Since it is a substance widely recognized and used in medicine, let's focus on taking you to a specific understanding.       1、 What is the serum separation gel composition?       In fact, it is a network structure composed of a large number of hydrogen bonds, appearing in the form of a transparent or semi transparent viscous colloid in front of everyone. Many manufacturers will accurately control their specific gravity, physiological inertia, viscosity and thixotropy during research and development, so that they can quickly and smoothly separate serum and plasma after contacting with blood, ensuring the stability of their components and the accuracy of experimental results.   serum separation gel       2、 Working principle of serum separation gel composition       Its working principle is that the specific gravity of the separated gel is 1.05, the serum is 1.02, and the blood clot is about 1.08. When it is centrifuged in the same blood collection vessel with the coagulated blood sample, the centrifugal force will cause changes in the hydrogen bond structure. At this time, the viscosity of the separated gel will also become lower, so that the blood clot can be transferred to the bottom of the tube, and the separated gel will turn over, forming three parts in the tube: serum, separated gel, and blood clot, so as to help medical personnel extract high-quality serum or plasma samples for testing.       3、 Where can I buy serum separation gel?       Although there are many businesses selling serum separation gel on the market, it is still necessary to choose carefully if you want to buy reagents with reliable quality and stable performance. As a manufacturer specializing in the production of serum separation gel, Desheng has experienced several decades of development. It has made continuous breakthroughs from the first generation of separation gel to the fifth generation of separation gel, and has further improved its key performance. At the same time, it has brought new products with excellent quality to the market. If you want to purchase, you can make it your preferred target.       As a direct selling manufacturer of serum separation gel in China, Desheng Company has independent plant and production equipment, and can supply a large number of goods at a preferential price at any time.

Key characteristics and preparation of serum separator gel         The serum separation gel is used in the vacuum blood collection tube. It is mainly the isolation material for the preparation of serum or plasma test samples. It can use its excellent performance to form a barrier between serum and plasma to prevent their material exchange, so as to achieve sample stability and facilitate the preservation and accuracy of test results.       1、 Key characteristics of serum separation gel       1. The surface of the precipitated serum sample is free of oil droplets and other precipitates, and long-term use will not block the sampling needle.       2. There is no wall climbing phenomenon. The separated gel is added to the test tube, and there is no wall hanging after being placed for a period of time.       3. It has physiological inertia and can minimize interference with experimental specimens.       4. Stable performance, less prone to aging, and stable memory storage for 2 years, without affecting the separation effect.       5. Equipped with radiation resistance, the irradiation dose can withstand the range of 8-25KG, and other properties will not change after radiation resistance.       6. There will be no backflow during transportation and storage.   Serum separating gel       2、 Preparation of serum separation gel       1. Add a 50% mass ratio mixture of butyl methacrylate, 2-mercaptoethanol, and 0.6 parts BPO of methyl methacrylate to a flask;       2. Stir and heat up. When the temperature reaches 85 ° C, a monomer mixture containing 0.6 parts of BPO butyl acrylate and additive mixed acid fat in the residue is dropped from the dropper funnel into the reaction flask, maintained at 85 ° C, and the monomer is dropped out within 3 hours; After continuing the reaction for 1 hour, cool to below 70 ° C to obtain an acrylic copolymer solution;       3. After 2 hours of vacuum distillation of the solution, remove the solvent toluene and unreacted monomers to obtain a polyacrylate solution;       4. Add 5 parts of hydrophobic silica gel to the polyacrylate solution, stir, and then vacuum defoaming to obtain the product serum separation gel.       Since the preparation of serum separation gel involves many fields, its technical content and production requirements are very high. The above method is the simplest and convenient one, but it is not applicable to all research and development, and should be adjusted according to its own requirements.   Barreled serum separation gel       3、 Precautions for use of separation gel       The reason why we talk about the use of serum separation gel is that it directly represents the quality of the separation results. The following two points are the most important points for attention, which should be paid attention to:       1. First of all, the quality of the separated gel should be emphatically investigated before use. Its specific gravity should be 1.045-1.065g/cm3, between serum and blood cells. Otherwise, it is not easy to turn over, resulting in poor quality of the extracted serum sample.       2. The use of centrifugation should be separated after the blood has completely coagulated, otherwise there is a tendency for fibrin to be mixed in the isolation layer, leading to hemolysis.       As the main supplier of serum separation gel, Desheng has always been leading other brands in the Chinese market. Its product performance is stable, and all key indicators are accurately controlled. The batch products produced are supervised and tested by professional quality departments, and it never sells fake and inferior separation gel.

Introduction to the performance and advantages of the serial separation gel       In recent years, serum separation gel has been indispensable in clinical blood testing. Its use as an additive in vacuum tubes has an undeniable effect, not only ensuring the accuracy of blood testing results, but also saving waiting time for medical staff and patients. Since it is an important additive, it is important for everyone to have an understanding of it during use, otherwise it may lead to unnecessary troubles, such as hemolysis, wall hanging, poor flipping, etc. Let's introduce it in detail below.       1、 What is serum separation gel?       As a high molecular compound, it is physiologically inert, insoluble in water, and has a large number of hydrogen bonds in its structure, which has good thixotropy and separation properties. Driven by centrifugal force, the reticular structure is destroyed, but it can be gathered together again in a short time due to thixotropy, thus isolating the blood. It is often used to separate serum and blood clots in yellow vacuum tubes.       2、 Is the performance of serum separation gel up to standard?       The measurement of whether the performance meets the standard mainly depends on the control of key numerical values such as appearance, specific gravity, and viscosity. Although many manufacturers produce serum separation gel in the market, the basic requirement for specific gravity is between 1.045 and 1.065g/cm3, because this is the only way to effectively separate blood. The appearance requirements are different, usually transparent, semi transparent, or opaque, without any impurities, and the viscosity needs to be maintained between 100000 to 300000 kPa, which is easy to add and thixotropic.   Barreled serum separation gel       3、 What are the other advantages of serum separation gel?       1. Hydrolysis resistance     At present, most of the separation adhesives used are acrylic and resin systems, which are hydrophobic materials with hydrolysis resistance. When in long-term contact with water or other reagents, there will be no reaction changes, so to some extent, the original properties of blood are guaranteed, which is conducive to the accuracy of detection results.       2. Radiation resistance     Because it is used in vacuum blood collection vessels, the basic requirement is to ensure that the collected blood components are not damaged. If there are bacteria in the tube, it will definitely interfere with the test results. Therefore, many manufacturers will carry out radiation resistance treatment. Generally, the separation gel with radiation resistance is not prone to aging, and the entire blood operation is carried out in a sterile environment, avoiding the occurrence of cross infection.         As a manufacturer of serum separation gel in China, Desheng has 18 years of research and development experience. Its product performance is not only stable and reliable, but also affordable. We have professional staff to receive every customer, ensuring one-on-one handling and coordination of subsequent problems.

serum gel separator tube       The serum gel separating tube is often used in the blood test center. Its main function is to separate the serum in the blood sample, facilitate the subsequent research and experiment, and help medical staff effectively judge the abnormality of the patient's body. However, it is not possible to separate serum with just one test tube, and it is necessary to rely on the serum separation gel in the test tube to achieve the goal. Why can the separation gel tube be used for blood separation? Let's talk about it in detail below.       1、 Serum separation gel       In fact, it is a kind of high molecular polymer, which is composed of various chemical components. As a viscous colloid separating serum and blood clots, it is physiologically inert. Because its structure contains a large number of hydrogen bonds, it has excellent thixotropic and separation properties. Usually, after the blood sample is collected into the test tube, it will be put into the centrifuge for operation when it is completely coagulated. Under the action of external force, the reticular structure will be destroyed, and it will gather together again due to thixotropy, so as to achieve the purpose of separation.   Barreled serum separation gel       2、 Method of adding serum gel       Generally, the separating gel is added to the test tube through the glue adding machine, and the standard amount of each tube is 0.8-1.2g. Note that the temperature of separating gel should not exceed 80 degrees. If it is difficult to add glue, water bath or other methods can be properly used for heating. The appropriate temperature is between 40-60 degrees, and the heating time should not be too long. After adding glue, put it into a 1500-2100 speed centrifuge for centrifugation for about 5 minutes. When sampling, use this tube containing separated gel to basically separate serum and blood cells, and effectively extract high-quality serum samples.       3、 Use of serum gel separation tube       The separation tube containing serum gel can be made of glass or plastic, and their operation is also different. Because the two have different clotting times for blood, the activation ability of plastic test tubes will be weaker, and the clotting time of blood will be longer than that of glass test tubes. Therefore, when using plastic separation tubes to collect blood samples, it is necessary to wait for about 4 hours until the blood is completely clotted before centrifugation on the machine. And during the placement process, it should be emphasized to separate the glass separation hose from the plastic separation hose to prevent confusion and centrifugation, leading to hemolysis.       As a supplier of blood vessel additives in China, Desheng has been researching and producing serum separation gel since 2005. After five generations of research and development, it continuously improves product performance, ensures customer experience, and gains market praise.

what comes first serum or gel       When checking their bodies in hospitals, many people go through the process of blood testing, mainly because the blood contains serum and plasma, which provide organic substances for the body. Once there is a disease, they first undergo changes, which is also the basis for effective judgment by medical staff. However, blood testing items are not always single and unchanging, and the requirements for different testing items vary. For example, for erythrocyte sedimentation rate testing, green heparin test tubes are required, while for routine serum testing, serum separation gel yellow tubes are required.       The yellow serum separation tube is the most widely used in clinical practice, as it can efficiently extract serum samples and obtain accurate detection reports in a short period of time. But in the actual operation process, sometimes it is found that the position of serum and glue is prone to change. What is this? Which one is on top?       1、 Performance of serum separation gel       Firstly, to accurately determine which separation gel is on top of the serum, it is necessary to fully understand the performance of the separation gel. As a hydrophobic organic compound, it is not only physiologically inert, but also has thixotropy and accurate specific gravity. When centrifugation is not carried out, it is generally located at the bottom of the test tube. But when the blood enters the tube and is completely coagulated, it is placed in a centrifuge. Due to its specific gravity ranging from 1.045 to 1.065g/cm3, while the serum has a specific gravity ranging from 1.026 to 1.031 g/cm3 and the blood clot has a specific gravity ranging from 1.090 to 1.095 g/cm3, the sequence presented after centrifugation and flipping should be that the serum is above the separation gel and the blood clot is at the bottom.         2、 The role of separation gel under serum       Due to the performance of the separation gel and the effect of external centrifugal force, it is located between the serum and the blood clot, which can effectively prevent the interaction behavior between blood cell components, ensure the stability of the serum sample, and also improve the efficiency of sample collection and the quality level of sample processing.       3、 The reason why the separation gel appears above the serum       Under normal circumstances, serum is always above the separation gel, but sometimes there may be cases where the serum flips below the separation gel. Why is this? In fact, this is related to its specific gravity. Accurate control of the specific gravity must be between the serum and blood cells. If it is too large or too small, it can lead to poor flipping or the situation where blood and separation gel are intertwined.       Based on the above introduction, I believe everyone already knows the location of serum and separation gel. The most important thing in the operation process is to ensure the reliable quality of the separation gel. As a professional manufacturer of serum separation gel, Desheng has been carefully researched and developed since its establishment, with precise formulation of key values, excellent flipping performance, and almost no poor separation effect.

gel serum separator tube       In early clinical medicine, the commonly used test tube was red, but now yellow tubes are widely used instead. This is mainly because yellow tubes contain serum separation gel substances, which can effectively help improve blood separation and detection efficiency. How to make good use of this gel serum separation tube in clinical practice? Let's take a specific look below.       1、 Advantages of yellow gel serum separating tube       Compared with the common red serum tube, the gel serum separation tube has many advantages that can not be ignored. First, it can realize on-line detection in the same tube without transferring serum samples, reducing detection steps and time. And it can also store and transfer serum samples in the original tube without interfering with the results of biochemical and immune tests, and the serum composition will not change.       2、 Basic properties of serum separation gel       In order to better use serum separation tubes, the first thing to understand is the separation gel, which is an inert reagent with strong stability, hydrophobic material that is insoluble in water, and resistant to high temperatures and oxidation. It is precisely these characteristics, combined with the action of centrifugal force, that enable the serum separation tube to effectively process blood, ensuring the extraction of high-quality serum samples.   gel serum separator tube       3、 Use of gel serum separating tube       1. After collecting the blood sample with the gel serum separating tube, slowly reverse and mix it for about 5 times as soon as possible, so that the blood sample can fully contact the reagent in the test tube, so as to ensure the quality of serum precipitation and avoid blood clamping.       2. After the sample collection is completed, place the test tube for half an hour and wait for the serum to completely precipitate before centrifugation.       3. If the blood collection environment is too low, the storage time of the blood sample should be appropriately extended, and the optimal storage temperature is around 25 degrees Celsius, so that serum precipitation can reach the ideal state.       4. Although the serum separation gel has a precise specific gravity and can be flipped under the action of a centrifuge, attention should be paid to the centrifugal speed and time. Improper operation can also lead to a decrease in the quality of the serum after centrifugation.       As a manufacturer of serum separation gel in China, Desheng has its own unique technology and rich experience, as well as large-scale production equipment. Its daily production can reach tons, ensuring the supply needs of customers. At present, it has become a hot selling product in the domestic market and is constantly developing internationally. Interested parties are welcome to choose Desheng to order. We hope that our services and products can bring the most enjoyable user experience to all customers.

serum separation procedure       Routine blood separation is a necessary step in clinical experiments, so we often see centrifuges used to separate blood in the blood testing department of hospitals. Most clinical tests do not test whole blood, but mainly use serum that has fibrinogen removed as the main test object. However, serum separation is not a simple matter. It requires a series of procedures to obtain effective serum samples to achieve experimental purposes.       1、 What is serum?       The essence of blood coagulation is that it contains fibrinogen, which can be transformed into insoluble fibrin, and then interwoven into a network, trapping a large number of blood cells to form gel like blood clots. Generally, after the collected blood sample tube is placed for about 1 hour, the clot after coagulation contracts and hardens, resulting in the extrusion of a clear yellow liquid called serum.   Serum separating gel       2、 Serum Separation Procedure       There are many methods for serum separation, so the procedures vary. There are generally two common methods:  

what causes serum to gel       In the daily blood testing work of hospitals, yellow test tubes containing serum separation gel are often used to collect blood samples, because the serum separation gel in the test tubes can quickly separate blood clots from serum, thereby obtaining high-quality serum samples for testing and analysis. However, during the operation process, serum coagulation still occurs. What is the reason for this? Many people suspect that it is due to serum separation gel, but is it related to it? Below is a specific analysis for everyone.       There are generally three reasons why serum coagulation occurs when using serum separation hoses:       1、 Sample placement time is too short       In fact, the coagulation process is relatively complex. When blood leaves the body, it coagulates because its coagulation factors are activated to convert into thrombin, which catalyzes the conversion of fibrinogen to fibrin. If the separation rubber tube is placed for too short a time, and the blood sample is not completely coagulated before being centrifuged, the blood cell components will be forced to leave the fibrin network during the operation process. In addition, the specific gravity of the serum separation rubber is small, and once the external force disappears, fibrinogen will remain in the serum layer, leading to coagulation.   Serum separating gel       2、 The patient used anticoagulant drugs       Many people suffer from diseases, and medical personnel will inject them with drugs such as baimei snake venom hemagglutinin and human prothrombin complex to promote blood coagulation. If blood samples are collected when drugs are used excessively or improperly, and the blood contains such anticoagulant drugs, even if they are separated, the serum will still contain residual anticoagulant components, which can lead to coagulation of the serum.       3、 Patient Disease Impact       Another reason for blood coagulation is due to abnormalities in the patient's own platelets. Blood is collected using a separation hose and separated. However, due to disease reasons, platelets can release many vasoactive substances that promote blood coagulation. This can also interfere with the blood serum under normal circumstances, resulting in blood containing clotting substances, which can promote blood coagulation.       In clinical blood diagnosis and analysis, the phenomenon of serum coagulation greatly affects the overall detection efficiency and delays. Understanding the causes can better help everyone avoid such problems.       Desheng is a supplier of a full range of blood collection additives in China, including serum separation gel, heparin sodium, heparin lithium, EDTA potassium salt, and other products. The product performance is stable, all of which are analytical grade, and can meet different experimental requirements.

what is serum separation       As a key link in clinical blood testing, the main purpose of serum separation is to obtain high-quality serum samples for testing. Because the isolated serum does not contain fibrinogen, it can provide nutrition and an environment suitable for cell survival in the human body. Through its detection, it can clearly understand whether patients have hidden diseases, facilitating medical personnel to carry out treatment and prevention work. So what is serum separation? How to obtain high-quality serum samples? Next, I will give you a specific introduction.       1、 What is serum separation?       In blood testing, serum and plasma as a whole are collectively referred to as "blood samples". However, during the analysis and testing process, traditional Chinese medical personnel do not directly operate with blood samples. First, they separate the serum from plasma in the blood, and only extract serum as a sample for testing. Especially in serological testing, serum separation is an essential operational step.       2、 Why choose a serum sample for testing?       In fact, the two main components contained in blood are serum and plasma. The difference between them is that serum does not contain fibrinogen, while plasma contains this substance. When testing and storing in vitro, the fibrinogen contained in it can change for various reasons, such as temperature or the addition of calcium ions. In this case, the plasma may form a gelatinous state, which is not conducive to experiments. Therefore, using serum for testing is the best option.       3、 Use of serum separating gel       The operation of serum separation is mostly carried out in the yellow tube of serum separation gel, because it contains a substance called separation gel. Relying on its stable performance, good thixotropy, and accurate specific gravity, it can ensure that the blood in the tube does not change, and can quickly complete serum separation, prevent material exchange between serum and blood clots, which is conducive to the stability of the test.       4、 Methods of serum separation       There are generally two methods for serum separation, namely, natural sedimentation and centrifugation. The natural sedimentation method is to place the collected blood test tube under normal temperature for a period of time, and after the blood naturally coagulates, the serum can be separated out. Although it is a common method, it takes a long time, which is not conducive to improving the detection efficiency. The centrifugation method is closely related to the serum separation gel. With the cooperation of the serum separation gel and the centrifuge, the reversal is realized based on the different specific gravity of the serum in the blood, plasma, and separation gel, which can quickly separate the serum and complete the detection.       As a professional supplier of serum separation gel, Desheng has clear specifications for its performance, physiological inertness, specific gravity, and viscosity, which can ensure rapid and effective separation of serum in experiments.

What are blood collection coagulants?       When conducting blood sampling tests in hospitals, most people will focus their eyes on vacuum blood collection vessels, but in fact, blood collection vessels are only a part of them, and the additives inside are the key, such as commonly used coagulants, anticoagulants, and serum separation gels, which can be added to blood collection vessels and applied to different test items. Recently, coagulant accelerators have been frequently purchased in the market, and many manufacturers have seized the opportunity to rapidly produce them. Therefore, there are more types of coagulant accelerators, so what are they? Let's focus on this aspect and introduce it to everyone.       1、 Rabbit Brain Powder Coagulant       This type of coagulant is a biological type and has few main applications. Its coagulation mechanism is to first promote plasma coagulation, then drive blood cells to coagulate during the reaction process, and then trap white blood cells through fibrin to achieve the goal of blood coagulation. It should be noted that it is susceptible to interference from external ambient temperature and is not easy to conduct coagulation promoting experiments under low temperature conditions.   Blood collection accelerator     2、 Coagulant activating enzyme coagulant       This is also a biological type of coagulant, and its mechanism of action is relatively similar to the first type of coagulant. The coagulant promoting effect is fast, but there may be poor blood clot contraction. As an enzyme preparation, thrombin has the characteristics of not being easy to preserve and inactivate, and is also susceptible to temperature effects, especially at low temperatures, where delayed coagulation is required.       3、 No type accelerator       The composition of this coagulant is mainly composed of silicon dioxide powder, dolomite, diatomite, etc. The key role is silicon dioxide. However, the amount of silicon dioxide added by different manufacturers during the preparation process varies, so the coagulant promoting effect also varies. Compared with the two aforementioned coagulants, it has its own unique advantages. It can activate the blood coagulation system as a whole, enabling rapid coagulation response, and achieving ideal coagulation promoting effects.       Judging from the overall situation in the current market, the standard for the use of coagulant enhancers is coagulation efficacy and performance indicators. Regardless of which one is selected, the most important thing is to use coagulant enhancers that meet your own experimental requirements. Desheng, as one of the manufacturers of coagulant enhancers in China, not only has advanced technology, but also has an excellent research and development team and service personnel. From customer ordering, delivery, and after-sales, there are dedicated personnel to receive and track, ensuring the customer's sense of use experience.

Do I need to shake up the blood collection accelerator?       The emergence of vacuum blood sampling additives not only provides convenience to major medical institutions, but also promotes more accurate testing results and reduces errors. Compared to traditional blood testing methods, blood is collected, tested, and analyzed in the original test tube, avoiding the possibility of cross infection to some extent. As one of the additives, coagulant enhancers generally appear in routine blood testing, which plays a role in promoting blood coagulation. However, in real life, many "novices" in hospitals do not know whether it is necessary to shake up blood samples containing coagulants? So let's focus on introducing it to everyone.       1、 Coagulant effect       Coagulant enhancers are often added to test tubes by machine or manual means, and are evenly sprayed on the inner wall to promote rapid blood coagulation. Due to the long waiting time for coagulation under natural conditions and the susceptibility to external interference that affects the accuracy of the results, the use of coagulants in test tubes has become extremely important and is one of the popular reagents in most medical institutions.   Coagulant accelerator       2、 Shake up the blood collection accelerator       In fact, it is necessary to shake the blood collection vessel containing coagulant promoting agent well, but pay attention to the strength. If the shaking force is too large, it is easy to cause damage to blood cell components, and eventually lead to hemolysis. If the shaking force is too small, the purpose of mixing may not be achieved, which will lead to poor coagulation promoting effect. It is recommended not to shake the coagulant promoting tube immediately when starting to pick it up. You can slowly invert it up and down to fully mix the coagulant promoting agent and blood.       3、 Precautions for use of coagulation promoting tubes       1. When using test tubes, special attention should be paid to the ambient temperature conditions. The ambient temperature should not be lower than 20 ℃. If it is lower than this value, it is not only necessary to increase the amount of coagulant added, but also to increase the mixing times and extend the coagulation promoting time.       2. Pay attention to the length of the coagulation promoting time. If the coagulation is not complete, it cannot be directly operated, otherwise it may easily lead to hemolysis.       3. Attention should be paid to placing the storage promoting coagulation tube at normal temperature, and it should not be stored under excessively high or excessive temperature conditions, which is not conducive to experimental detection.       As a professional supplier of coagulant enhancers, Desheng not only has reliable product quality, but also has perfect after-sales service.
