Test indicators and precautions for serum clot activator

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

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.

Latest company new about serum separation tubes with gel
2023/04/21

serum separation tubes with gel

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.

Latest company new about Principle and operating points of serum separator gel tube
2023/04/19

Principle and operating points of serum separator gel tube

Principle and operating points of serum separator gel tube       In the early stages, most hospitals would wait for the blood to naturally coagulate after blood collection, and then undergo centrifugation. This process not only took a long time, but also affected the functionality of various analytical instruments. In order to rapidly promote the development of detection technology and effectively improve efficiency, blood sampling additives have gradually emerged, such as separation gel, coagulant, anticoagulant, etc. Among them, the use of serum separation gel tube has become an indispensable product in the clinical laboratory. As an important guarantee for the quality of routine blood collection, it not only reduces the difference of detection results, but also effectively avoids various blood cross infections, and prepares high-quality serum samples. Here we will analyze the serum separation gel tube.       1、 Principle of separating serum and blood clot by serum separating gel       As a hydrophobic organic compound, its appearance is a viscous colloid with thixotropic properties. Because its structure contains hydrogen bonds, it can form a network structure through association, and then the network structure is destroyed under the action of centrifugal force. After the centrifugal force disappears, it returns to the original colloidal appearance due to thixotropy. Generally, the specific gravity of the separated gel is about 1.045, while the specific gravity of the serum is 1.02, and the blood clot is 1.08. When the blood sample is collected by using the separated gel tube, it will quickly turn over under the action of centrifugal force, forming three parts of serum, separated gel, and blood clot in the tube, so that medical personnel can achieve the purpose of serum extraction or detection from the original tube.   serum separator gel tube       2、 Gel procoagulant tube for serum separation       The separating gel tube contains not only separating gel, but also accelerating agent, which is also added in clinic to quickly separate and promote blood coagulation. After processing, it is sprayed into the separating gel tube. Due to the fact that blood can only be centrifuged on the machine after complete coagulation, the use of coagulants can accelerate the blood coagulation time and ensure the stability of blood coagulation, without causing fibrin to be mixed in the isolation layer.      3、 Key points of operation of gel tube for serum separation       1. During the process of centrifugation on the machine, attention should be paid to the control of speed and time. Generally, centrifugation at 3000r/min for about 5 minutes is sufficient.       2. After collecting blood samples with gel tube, slowly rotate the test tube for about 5 times as soon as possible, place the blood sample for about half an hour, and then separate it after the blood is completely coagulated.       3. Blood separation or serum testing can be achieved on the original tube without transfer. If transfer is required, attention should be paid to using sterile matching test cups for examination.       As a professional manufacturer of serum separation gel, Desheng has 18 years of R&D and production experience and strong strength. It supplies many enterprises in China. Due to its independent factory line and warehouse, it can meet the needs of large-scale ordering and shipping.

serum separator tube gel name

serum separator tube gel name       In recent years, with the rapid development of medical testing technology, the application of serum separation tubes has become increasingly common, and even become an indispensable item in medical research and clinical testing. The reason why it is so valued is mainly because it can quickly and effectively separate the serum in the blood sample, facilitating subsequent research and diagnosis.       1、 Name of gel in serum separating tube       There are generally two kinds of materials for serum separation tubes, plastic tubes and glass tubes. A layer of separation gel will be added to the tubes made of these two different materials. It is also known as the "serum separation gel", which can efficiently isolate serum and blood clots in the blood, allowing serum to accumulate separately above the separation gel, making it convenient for medical staff to sample and test.       2、 Applicable inspection items for serum separation tube       The serum separation tube is suitable for various clinical examinations, such as routine blood analysis, liver and kidney function tests, serological tests, and enzymatic tests. Because the serum separation gel it contains can effectively obtain serum samples with high purity and no interfering impurities, which can fully ensure the accuracy and reliability of experimental results.         3、 Principle of action of serum separation tube       Its working principle is achieved by relying on the substance serum separation gel, which can quickly separate blood through its own chemical properties, such as specific gravity, viscosity, physiological inertness, etc. At the same time, due to the external centrifugal force, it will flip to the center of the serum and blood clots, preventing them from exchanging substances and ensuring the stability of serum components and plasma.       4、 Precautions for using serum separation tubes       Although the use of serum separation tubes is relatively simple, in order to ensure the accuracy of experimental results, some issues still need to be noted:       1. The samples in the serum separation tube need to be stored in a standardized manner, and the separation and testing should be completed within the established time frame. Do not leave them in a high temperature environment for a long time. Usually, the suitable storage temperature for separated serum is between 2-8 degrees Celsius, and the storage time should not exceed 24 hours.       2. Before use, it is necessary to check whether the separation tube is damaged and whether the separation adhesive inside is mixed with unknown impurities. If there are any abnormalities, it should be replaced immediately and cannot be used again. Pay attention to the setting of centrifugation time and centrifugation speed during the centrifugation process.       As a manufacturer of serum separation gel in China, Desheng not only has 18 years of professional research and development experience, but also has stable performance of separation gel products, which can be used in various clinical experiments without any interference.

Latest company new about stacking gel separating gel difference
2023/04/13

stacking gel separating gel difference

stacking gel separating gel difference       As a polymer, separation adhesive has undergone several generations of changes and upgrades since its emergence, and its key performance has also been qualitatively improved in various aspects. However, due to the differences in raw materials and production methods used by manufacturers, several different types of separation adhesives may appear, such as commonly used separation adhesives with acrylic acid, resin, and silicone rubber systems. Recently, there has been the emergence of concentrated glue again. What substance is it? What is the difference between it and the separation adhesive?       1、 What is concentrated adhesive?       It mainly refers to that in discontinuous polyacrylamide gel electrophoresis, the gel concentration as the same medium will be divided into two types, namely, the negative electrode concentration is 2% - 5%, and the remaining concentration is 6% - 8% as the separation gel.   Barreled serum separation gel       2、 The difference between concentrated adhesive and separated adhesive       1. Differences in nature       From the performance of concentrated gel, it can be seen that it is a part of discontinuous polyacrylamide gel electrophoresis, while the separating gel is a part of polyacrylamide gel in discontinuous buffer system. Its composition, pH value and gel pore size are significantly different from those of concentrated gel.       2. Differences in reaction processes       The reaction process of concentrated gel is obviously different from that of separation gel. Because the former has low gel concentration and larger pore diameter than that of separation gel, the resistance of charged protein or nucleic acid ion gel is small and the movement speed is fast. Once it is close to the small pore gel, the resistance becomes larger and the speed slows, which will concentrate the sample. However, the separation gel has high concentration and small pore size. Due to the role of molecular sieve, small molecular substances are easy to pass through, with small resistance and fast moving speed. At this time, they will be separated from gel by molecular sieve effect according to the difference of molecular weight.       3. Differential effects       Based on the performance of both, it can be clearly known that the concentrated gel has the function of reducing the resistance of ion movement and has the function of stacking, which can concentrate the diluted sample into a relatively tight state. At the same time, it also has stability, allowing proteins to aggregate at the moving interface, concentrate into intermediate blocks, and stabilize the entire reaction interface. The separation gel has many functions, the most important of which is prepared by the manufacturer. It can be added as an additive to vacuum test tubes to separate blood, ensuring the stability of serum components, and providing accurate and accurate data results for medical staff.       As a professional manufacturer of serum separation gel in China, Desheng not only has 18 years of research and development experience, but also has an independent production line that can produce in bulk according to customer needs.

Latest company new about what is serum separator gel made of
2023/04/12

what is serum separator gel made of

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.

Latest company new about serum separator gel composition
2023/04/11

serum separator gel composition

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.

Latest company new about Key characteristics and preparation of serum separator gel
2023/04/10

Key characteristics and preparation of serum separator gel

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.

Latest company new about Introduction to the performance and advantages of the serial separation gel
2023/04/07

Introduction to the performance and advantages of the serial 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.
