heparin sodium classification       Heparin, as a naturally occurring substance in animal liver, has been found to have anticoagulant effects. Therefore, many manufacturers have prepared heparin sodium or heparin lithium raw materials based on it for use in vacuum tubes. But they don't just have one function, they can be applied to different aspects through different categories, and their categories and prices also vary. Many people increase their purchasing costs because they don't know the classification, which sometimes brings a lot of trouble for experiments. So in response to this situation, let's take heparin sodium as an example and introduce the classification in detail. Later on, we can also differentiate and purchase.   Bottled heparin sodium       1、 Analytical grade heparin sodium       The main source of its extraction is pig small intestine mucosa, but the production process is fine, with strict numerical requirements. The finished product is a white powder, easy to dissolve in water, with an average molecular weight of around 15000 and a potency between 150IU-180IU. It is formulated as a solvent and added to vacuum blood collection vessels to have an anticoagulant effect on blood.       2、 Low molecular weight heparin sodium       It is mainly used for medical injection into the human body, and its production requirements are generally stricter than other types of heparin sodium, and its price is expensive. It can be used to treat large diseases such as thrombosis in the human body. Although it is also composed of a mixture of polysaccharide chains, its average molecular weight is between 4000 and 5000, which is much lower than the analysis of pure heparin sodium. It also has strong anticoagulant effects and has fewer complications in clinical treatment of thrombosis.       3、 Cosmetic grade heparin sodium       This is a raw material in cosmetics, which is usually added to the skin care products of redness, swelling and acne gel. The addition amount is about 0.6%, which can use its anticoagulation, thrombosis and blood viscosity reduction effects to improve the skin permeability, improve the local skin blood circulation, and is conducive to the nutrition supplement of the skin, which has a good maintenance effect.       There are roughly three categories of heparin sodium mentioned above. There are differences in the production processes and requirements of these three types, and their prices also vary. Please choose according to your own usage. As a professional manufacturer of heparin sodium, Desheng sells heparin sodium products that are analytical pure for external use and cannot be directly used in the human body. When purchasing, users can express their purpose clearly, which is convenient for customer service to provide accurate answers.

Preparation Steps and Extraction Methods of Heparin Sodium Porcine       Heparin sodium, as an anticoagulant reagent, is usually added to vacuum tubes for medical staff to use. Currently, the most widely sourced source of heparin sodium on the market is extracted from the intestinal mucosa of healthy pigs. However, due to the large amount of impurities and bacteria in the heparin sodium directly extracted from pig mucosa, it requires manual separation and preparation to obtain high-quality heparin sodium raw materials.       China has a vast territory, a large-scale animal husbandry industry, and abundant pig resources, making it a major country in extracting heparin. Nowadays, most domestic manufacturers also extract crude products from pig intestines and make them into high-quality products for sale. Although the extraction methods are unified, there are still differences in their respective preparation methods. Below, we will discuss in detail how to prepare heparin sodium extracted from pig mucosa?       Steps for extracting heparin from live pigs      1. Bowel washing: Clean the feces inside the intestine, and then soak the pig intestines filled with water in water for a day. If the temperature is too high in summer, add ice to the soaked water.       2. Intestinal scraping: Generally, a scraping machine is used to operate. The soaked pig intestines are placed in the scraping machine, and the mucosal surface of the intestine is scraped. Then, the casing is scraped to obtain a complete and undamaged casing.       3. Irrigation: Rinse the scraped casing with clean water, remove any impurities left during the scraping process, and then check if the casing is damaged or spoiled.       4. Salt pickling: Spread the casing evenly, fully apply the specialized salt required for production to each part, marinate for one day, repeat the operation the next day, then put it into a tank to drain the salt water, and then refrigerate at low temperature to prevent spoilage.   Heparin sodium powder       Extraction method of crude heparin sodium       1. Resin treatment: Pour a certain amount of heparin sodium specific resin into the cylinder, wash off impurities adhered to the surface of heparin sodium with water, and then remove water before pouring it into alcohol and letting it stand overnight. Then remove the alcohol and pour it into 40 degree hot water to wash away the remaining alcohol smell in the cylinder. Soak it in a calculated hydrochloric acid solution and stir repeatedly during this process.       2. Salt hydrolysis: Put the scraped casing into the mixing tube, add water and specialized salt for casing processing, stir thoroughly, and then add alkaline substances to adjust the pH value, heat up and filter.       3. Adsorption: Pour the pre processed heparin sodium resin into the adsorption tank and stir, accurately control the concentration of the adsorbed solution, and use a filter screen to remove the heparin sodium resin.       4. Washing: Wash with professional processed salt from the casing, stir the heparin sodium resin twice at intervals, pour the washing solution, and wash away any interfering substances adsorbed in the resin.       5. Precipitation drying: After washing, add alcohol and stir, cover and seal, and then place in a low-temperature refrigeration room to precipitate for 24 hours. Collect the paste heparin, and then use the precipitate to load a plate and dry it in a 60 degree drying oven for 3 hours to obtain the crude heparin sodium.       After the above steps, crude heparin sodium can be obtained, and on top of it, refined heparin sodium can be prepared for use. As a professional manufacturer of heparin sodium, Desheng takes every step to extract heparin from pig intestines and manually prepare it, providing customers with on-site inspection opportunities.

Does heparin affect sodium levels？       As a natural anticoagulant reagent, heparin usually contains two types: heparin sodium and heparin lithium. Normally, the intake and excretion of sodium in the human body should be balanced. However, in clinical practice, medical staff using heparin tubes for electrolyte analysis may find that sodium levels are higher than normal reference values. Why is this? Some people suggest that the addition of heparin leads to an increase in sodium levels. Is this really the case? Based on this question, let's carefully analyze it for everyone.       Based on the questions raised, Desheng also conducted analysis and research on this, comparing blood samples collected using test tubes with and without heparin to analyze whether the extracted detection components have been affected. The experimental results showed that heparin anticoagulation had a significant effect on blood potassium, but had no significant effect on sodium levels. From the analysis, it can be seen that heparin substances are prone to react with potassium ions contained in the blood sample to generate heparin potassium, interfering with the determination of potassium by ion selective electrodes, resulting in a low potassium ion content in the analysis results.   Bottled heparin lithium       In addition, from the serum samples, it can be seen that due to the destruction of platelets in the blood, they cannot aggregate and release potassium ions, resulting in a serum concentration greater than that of plasma, and the degree of enhancement is proportional to the number of platelets. During the experiment, due to the fact that platelets have been destroyed and cannot accurately reflect the true level of potassium in the body, the use of heparin tube detection will directly affect the determination of potassium ions, without affecting sodium levels.       From the source of heparin, it can be inferred that it is used as a natural anticoagulant reagent and its function in contact with blood in test tubes is to prevent blood clotting. If it affects other components of the blood, it not only indicates poor quality of heparin, but also requires careful selection. However, in practical clinical applications, its use is widespread, especially in biochemical diagnosis, where heparin is used to ensure the accuracy of analysis results and improve efficiency. If it affects sodium levels, it is likely that clinical practice will use these types of test tubes with caution, rather than using them in large quantities.       As an experienced manufacturer of raw materials for blood collection reagents, Desheng has a wide range of product types, including serum separation gel, heparin lithium, heparin sodium, EDTA potassium salt, coagulant enhancer, silicifying agent, etc. These products are of analytical purity and have stable performance, which can be selected and used by blood collection manufacturers. And the separation adhesive products are supported by independently developed patented technology, ensuring that customers have no worries about using them.

Gel serum separation method and precautions       With the improvement of people's health awareness, blood testing has become more common, and most disease diagnoses also need to start from the patient's blood, using instrument and equipment data for comparison, in order to effectively help improve the disease diagnosis rate. To fully ensure the accuracy of the results, the first step is to do a good job in blood collection and separation, in order to obtain high-quality serum samples and improve overall detection efficiency.       1、 How to collect blood       In the early stage, the method of collecting blood in clinic was to use glass tubes without any additives, but there were many drawbacks, such as: long time storage, not obvious separation effect, which would affect the normal blood separation work, so later the appearance of separation gel slowly stopped using this method to collect blood.   Serum separating gel       2、 Gel serum separation method       The initial method of serum separation was the more common water bath centrifugation. Although the separated serum samples can be used for testing and analysis, if the storage time is extended, the serum will undergo changes, leading to inaccurate data. Such sample detection is of little significance. After the appearance of the separated gel, this method is no longer used.       The method of separating serum by gel mainly depends on gel. Because there are a lot of hydrogen bonds in the structure of separating gel, it can quickly and efficiently separate serum from blood clots according to specific gravity, viscosity, physiological inertia and other indicators. For stored serum samples, they can be stored for a long time without any changes or abnormal test results.       3、 Precautions for gel serum separation       It is worth mentioning that during serum separation, attention should be paid to the use and operation of gel tubes, of which the more important two points are to ensure the complete coagulation of blood and the control of centrifugation. The specific details are as follows:       1. After collecting the blood sample with gel tube, shake it slowly and evenly, then place it for half an hour, and centrifuge it on the machine after full coagulation.       2. The control time for centrifugation operation should be 10 minutes at a speed of 3500 to 4000. After centrifugation, it is also necessary to let it sit for a few minutes until the serum and blood clots are completely separated before using the instrument for detection.       Separation gel is very important in the process of extracting high-quality serum samples, and selecting a reliable separation gel supplier is the key factor. Desheng is a professional manufacturer of serum separation gel. It has never interrupted the research and development of separation gel for 18 years. After five generations of sophisticated production, it was able to provide customers with high-quality separation gel, which was highly praised.

Introduction to ethylenediaminetetraacetic acid dipotassium salt dihydrate       Due to the fact that medical staff analyze patients' conditions based on abnormalities in various blood indicators, blood sample testing has become one of the important and necessary procedures in clinical practice. The early collection and analysis of blood samples were all manually operated, and later gradually developed into fully automated operations. As a blood processing reagent, the application of ethylene diamine tetraacetic acid dipotassium salt dihydrate also promoted the development of automated blood testing.       1、 The Effect of Ethylenediaminetetraacetic Acid Dipotassium Salt Dihydrate       There is often a difference between ethylenediamine tetraacetic acid dipotassium salt and ethylenediamine tetraacetic acid dipotassium salt dihydrate in the market. As an anticoagulant reagent in blood collection, the advantage of dihydrate will be very obvious. Because it contains two water of crystallization, compared with the anhydrous dipotassium EDTA, it has weaker moisture absorption capacity, stronger stability, is not easily affected by moisture, and is conducive to storage and use.   EDTA dipotassium       2、 Anticoagulant principle of ethylenediaminetetraacetic acid dipotassium salt dihydrate        As a popular anticoagulant reagent, its demand is increasing. The principle of action is that it is an amino polycarboxylic acid that can be close to calcium in blood samples. When complexed with calcium, prothrombin cannot be converted into thrombin and has minimal impact on blood cell components, thus achieving anticoagulant purposes. Generally, 4 ℓ of ethylenediaminetetraacetic acid dipotassium salt dihydrate corresponds to 2 milliliters of anticoagulant blood, but it must be a dihydrate with a purity of over 99%, otherwise the test results may be inaccurate.        3、 Addition and use of ethylenediaminetetraacetic acid dipotassium salt dihydrate       Due to the powdery nature of the produced ethylenediaminetetraacetic acid dipotassium salt dihydrate, it needs to be prepared into a solution when added to a test tube. Deionized water is often used to dissolve and mix, and then the solution is sprayed onto the tube wall by machine or manual means for drying. Due to the retention of water in the tube wall, clinical blood collectors should quickly mix it upside down and make it fully contact with the blood in order to achieve the best anticoagulant effect.       As a professional manufacturer of blood vessel additives, Desheng has a complete range of product types, all of which are analytical grade. Additionally, the potassium salt of ethylenediaminetetraacetic acid has two properties of anhydrous and dihydrate as reagent raw materials, which can be chosen by customers themselves. At present, the domestic market has a high level of satisfaction with the use of blood collection additives produced by the company, which has been recognized by multiple customers.

Introduction to the Performance, Formulation, and Addition of Dipotassium Ethylenediaminetetraacetic Acid       Dipotassium ethylenediaminetetraacetate, as a commonly used reagent in clinical blood testing tubes, is suitable for various biochemical tests and provides effective value reference for clinical diagnosis, analysis of data, and treatment due to its ability to form stable complexes with calcium substances in blood samples, which can interfere with the coagulation process and prevent blood coagulation. Let's have a detailed discussion here.       1、 Performance of potassium ethylenediaminetetraacetic acid   Its appearance is white crystal powder, odorless, and soluble in water. As the finished product is in powder form, it is easy to absorb moisture, with a main content of over 99%. It is of analytical purity and can be prepared into a solution to be sprayed on the inner wall of the test tube when used. As it does not affect cellular components and can fully inhibit platelet aggregation, it is widely recognized in clinical use as a blood treatment reagent and is also recommended as an ideal anticoagulant reagent in the industry.      EDTA potassium powder       2、 Preparation of potassium ethylenediaminetetraacetic acid solution       Based on its performance, it can be determined that it is easily soluble in water, so the preparation process is also very simple. Prepare deionized water to dissolve to the required capacity. Due to the possibility of powder residue on the bottle mouth or inner wall of the instrument during the preparation process, in order to avoid excessive concentration or dilution of deionized water, the amount of potassium dioxide solution added to the test tube will be controlled. If it is necessary to increase the amount of potassium dioxide added, the preparation concentration can be increased first before considering whether to increase the spraying frequency. During this process, attention should be paid to formulating according to the test tube standard to avoid excessive concentration that may cause the experiment to fail.       3、 Addition amount of potassium ethylenediaminetetraacetic acid       According to industry standards, the addition amount is 1.5 to 2.2mg of potassium ethylenediaminetetraacetate per milliliter of blood. When preparing the reagent, the median value is 1.8mg/ml. Due to different experimental requirements, the addition amount can also be flexibly adjusted during use. Additionally, it should be noted that potassium ethylenediaminetetraacetic acid can be used in combination with sodium fluoride. When they are placed together in a test tube, the amount added may change, usually by adding 1.2-2.0 milligrams of potassium dioxide per milliliter of blood, and 2- 4 milligrams of sodium fluoride.       As the raw material supplier of blood collection tube additives, Desheng produces serum separation gel, EDTA potassium salt anticoagulant, accelerator, silicating agent and other products with stable performance and analytical purity. Adding them into the vacuum blood collection tube can effectively help experimental detection. If you are interested, please click on the website to inquire and purchase!

serum clot activator tube with gel separator       Previously, blood samples were collected and placed for a period of time to naturally coagulate before waiting for serum to precipitate. This not only took a long time, but also greatly affected the functionality of the analytical instrument. In order to rapidly promote the development of detection technology, it was developed to add serum clot activator and separation gel into the test tube. The combination of these two substances is also called serum separation gel coagulation promoting tube. Its appearance is the key to quality control in the blood collection process, and it also helps medical staff prepare high-quality serum samples, reducing the possibility of cross infection. So let's take you to a specific understanding below.       1、 Serum separation gel activation tube       In fact, this test tube is called blood coagulation promoting tube, which contains two substances: separating gel and coagulant. The coagulant is a kind of reagent developed in clinic to quickly promote blood coagulation. Generally, it is composed of silica powder, emulsifier, surfactant and other components, and then it is processed to obtain the powder. When it is used, it is prepared into a solution, sprayed on the inner wall of the test tube containing separation gel, and then placed in an oven for evaporation and drying. Although there are activators that can quickly coagulate blood, it is still necessary to observe whether the blood has completely coagulated before separation and extraction, otherwise it may lead to fibrin inclusion in the isolation layer and contamination of the serum sample.         2、 Activate the blood clotting time inside the tube       Although fully automated analytical instruments can detect thousands of samples per hour, the speed of separating serum samples in the laboratory cannot keep up, which directly affects the overall detection efficiency. The most important factor is the speed of blood coagulation, which is not only related to the material of the test tube, but also directly related to the temperature. Usually, coagulation factors can be quickly activated in glass test tubes, requiring a temperature condition between 23 and 25 degrees Celsius for 1 hour. However, plastic tubes have weak activation ability, and blood can only fully coagulate in 2-4 hours.       3、 Significance of gel activation tube for serum separation       Due to the fully automated operation of clinical laboratory centers, a large number of instruments are used during the blood collection process. If one step is wrong, it will pose a hidden danger to the experiment. This not only affects the collection of blood samples, but also makes it meaningless to separate serum. By using a separation gel activated tube, it can reduce waste items, complete collection and detection on the original tube at once, without the need for other instruments, and the steps are reduced, which has great significance for the safety and efficiency of current medical testing.       As a raw material supplier for blood vessel additives, Desheng has a complete range of product types and series, which can meet different experimental needs of customers, and has reliable quality and worry free use.

what is serum gel blood test for       As an indispensable reagent in clinical medical detection, serum gel can isolate serum and blood clot during blood test due to its stable performance, which generally appears in biochemical indicators, immunological tests, coagulation mechanism and other detection and analysis. Due to its convenient use in blood testing, simple and fast processing steps, and the ability to obtain high-quality serum samples, it has become one of the reagents that hospitals are passionate about using. Although serum gel has obvious advantages, many people still do not know what serum gel blood test is? In fact, to understand what serum gel blood test is, you need to first understand the relevant knowledge of serum gel. You can focus on the following three points:       1、 Key performance of serum gel        The key performance of serum gel is its specific gravity, viscosity and physiological inertia. The specific gravity determines whether it can turn over during the processing of blood samples to separate serum from blood clots. And viscosity represents whether it is convenient to add to the test tube and whether it will be affected by temperature during transportation. Physiological inertness represents whether it will interfere with blood components and whether its stability is strong enough. Based on these important properties, the addition of serum gel into the test tube will not affect the blood test, which is also an aspect that everyone must pay attention to when selecting serum gel.   Serum separation       2、 Dose of serum gel added to test tube       In terms of the dosage, the judgment standard is very intuitive. No matter what kind of blood collection tube is and what its diameter is, after the injection of serum gel, the thickness of gel should always be greater than or equal to 6mm. If this thickness is not reached, the isolation effect between serum and blood clot is likely to be poor. Even if the isolation can be achieved, the medical staff will not be able to distinguish whether there is serum gel in the test tube because of the insufficient amount of separation gel. However, sometimes it will be adjusted according to the actual situation. For example, 0.8g of serum gel will be used for test tubes with diameter ¢ 13, and 1g of gel will be used for test tubes with diameter ¢ 16, and then observe whether it reaches 6mm according to the added amount.      3、 Blood test with serum gel tube       As the detection object in clinical biochemical items, serum samples are tested with serum gel. In fact, gel is not directly used to complete blood detection, but only used as a blood processing reagent. Through special performance, blood samples are separated and high-quality serum or plasma samples are obtained before testing, which is an important step in the blood testing process. At the same time, because the treatment, analysis and preservation of blood samples are completed in one tube of serum gel, cross infection is directly avoided during blood test.       As a supplier of serum gel, Desheng has become a hot selling product in the domestic market because a professional team strictly controls the performance, which can ensure stable use of customers and no interference in experiments. Currently, we are continuously strengthening our cooperation with foreign clients. If you are interested, please click on the website to inquire and purchase!  

Test indicators and precautions for serum clot activator       Serum samples, as one of the important clinical test specimens, were extracted by most medical institutions in the past by collecting blood samples and automatically precipitating them after complete coagulation of the blood. But usually, the natural coagulation time of blood after leaving the human body is long, which is not only difficult for medical staff to extract, but also difficult to ensure whether the extracted specimen is qualified. This method is basically difficult to meet the requirements of rapid laboratory testing, and the emergence of serum clot activators has fully improved this situation. Below, we will introduce it in detail.        What is a serum clot activator?       Serum clot activators, also known as "coagulants", have the function of activating coagulation factors, promoting the generation of thrombin and fibrin clots in the blood, accelerating the contraction of blood cell coagulation, and thus achieving the goal of rapid serum extraction.   Serum separating gel      What are the test indicators for serum clot activators?       1. Initial setting time: After adding the activator to the test tube and fully contacting the blood sample, the appearance of the initial setting with the naked eye will be similar to that of a jelly sample. Although there is a setting phenomenon, it still oscillates.       2. Deep coagulation: The vacuum tube can be picked up and slowly shaken, and if there is a clear and visible blood clot indicating deep coagulation.       3. Complete coagulation: Shake the test tube until the blood clots inside the tube remain almost stationary.       4. Place it in a centrifuge for centrifugation, set the time and speed that meet the experimental requirements, and observe whether the serum appearance is transparent and there is no blood entrapment phenomenon after completion.       What are the precautions for using serum clot activators?       To achieve the goal of promoting coagulation, it is first necessary to pay attention to the ambient temperature. If the temperature is too low, corresponding changes should be made to the dosage and mixing frequency to ensure sufficient coagulation time, or the temperature should be controlled using a water bath.       Ensure complete coagulation, and serum cannot be extracted without complete coagulation in the blood, which can easily lead to hemolysis and damage to cellular components, making it impossible to extract high-quality serum samples.       As a professional manufacturer of serum clot activators, Desheng has a well-established R&D team and skilled R&D technology. The products produced have stable performance, high main content, smooth customer use, and no secondary cargo problems. Currently, it is very popular in the domestic market.

Usage and precautions for the serum clot activator tube       Clinical blood testing is usually specified based on the type of specimen, for example, common specimen types include serum, plasma, and whole blood. These different specimen types have different examination items. Although the examination items are different, the collection of these specimens is basically completed through vacuum blood collection. There are various types of test tubes used in hospitals to collect blood samples, such as anticoagulant tubes, coagulation promoting tubes, etc. Common serum clot activating tubes are coagulation promoting tubes, which can use extracted serum samples to complete biochemical testing. Next, let's talk specifically about serum clot activation tubes.   Bottled accelerator       Addition of serum clot activator       Due to the fact that most of the serum clot activators produced on the market are in powder form, they need to be added to blood collection vessels to form an anhydrous ethanol suspension, which is then sprayed onto the inner wall of the test tube, placed in an air drying box for drying before use. Due to its ability to activate fibrinolytic enzymes, soluble fibrin can be transformed into insoluble fibrin, which can quickly promote coagulation and is suitable for emergency serum biochemical experiments.       Use of serum clot activation tubes   Due to the uniform distribution of serum clot activators on the tube wall, after collecting blood samples, it is necessary to gently rotate the tube 4-5 times to make it fully contact with the reagent, and then let it stand for about 30 minutes. After the blood sample is completely coagulated, centrifuge to obtain the serum. Note that if the room temperature conditions are too low, it can be left in a 37 degree water bath for about 20 minutes.       Precautions for using serum clot activation tubes       1. The activation and coagulation of blood samples are closely related to temperature conditions, degree of mixing, performance of clot activators, and blood collection volume. The most critical factor is temperature. If the ambient temperature is too low and there is no water bath, it is necessary to adjust the amount of reagent added appropriately to extend the coagulation promoting time.       2. Attention needs to be paid to ensuring that the blood sample in the test tube is completely coagulated. If the coagulation is not sufficient, it can cause hemolysis and fibrin filament wall hanging phenomenon, which cannot completely separate the serum and affect the experimental process.       3. Pay attention to the control of coagulation time, which is not easy to be too short, otherwise it may lead to the precipitation of fibrin filaments, floating in the serum, and causing instrument blockage.       Although there are many manufacturers producing coagulants, each has its own quality advantages and disadvantages, and choosing a supplier with excellent quality is the key. As a supplier of blood vessel additives, Desheng has established a comprehensive model for product production at the source due to its independent research and development team and production line, which has been praised by customers.

serum separation tubes with gel       The gel serum separating tube is a test tube commonly used in clinical blood centers. The inside of the tube is mainly added with separating gel, but sometimes other reagents are added for common use, such as coagulants. Due to the high-quality finished tubes appearing in front of everyone during the blood drawing process and being used directly, it is difficult for the naked eye to detect their presence inside the tubes, which is also a detail that many novice operators in hospitals tend to overlook. They don't know how to use this gel serum separation tube, so the following details will be introduced to you.       1、 Reagent addition of gel serum separation tube       When the gel in the tube is in full contact with the blood, it can separate the blood and completely separate the serum from the blood clot. If it is used together with the coagulant, the separation speed will be faster to ensure that the test results will not be biased. Generally, the separated gel does not need to be prepared and directly added to the test tube, while the coagulant is in the form of powder. If it needs to be used, it needs to be prepared into a solution, and then sprayed on the inner wall of the test tube for drying.   Serum separating gel       2、 Use of gel serum separating tube       After the blood collection of the separation tube is completed, the user should pay attention to slowly rotating the test tube about 5 times, and the amplitude of the movement should not be too large, so that it can come into uniform contact with the reagent. Then let it stand for about half an hour, wait for the blood sample to completely coagulate, and then put it into a centrifuge for operation. At this time, the centrifugation speed and time need to be controlled. If the centrifugation rate and time are not properly controlled, the separation of gel will not work. If it cannot be overturned, it will cause hemolysis when the blood sample is mixed with gel.       3、 Problems of gel serum separating tube       In reality, due to the lack of experience of many clinical staff, the use of gel serum separation tube in the actual operation process led to the blockage of the analytical instrument caused by fibrin residues in the serum. If the condition of complete blood coagulation is excluded, it is related to the quality of gel. Although there are many businesses selling separation gel, there are still many inferior products, so we must pay attention to them when choosing. If the experimental process is very smooth, wait for the serum to be completely separated, let it stand for a few minutes, and then use the machine for testing and analysis. It cannot be immediately taken out for use, otherwise it will also cause poor testing results.       Desheng is a professional supplier of serum separation gel in China. The separation gel has accurate specific gravity and good overturning performance. In case of any problem, it will be answered comprehensively. Currently, we have signed contracts with over 1000 customers both domestically and internationally for long-term supply.
