In serum testing, coagulants can be selected to rapidly coagulate blood, while in whole blood or plasma testing, different anticoagulants are selected to prevent coagulation of collected venous blood.What are the commonly used anticoagulants? Hubei Xindesheng Materials Co., Ltd. has compiled some points of anticoagulants for us.   Citrate The anticoagulation principle of citrate is forming a chelate with calcium ions in the blood to prevent blood coagulation,such as sodium citrate.The color of citrate blood collection tubes are blue or black head.The ratio of anticoagulant to blood in the blue head tube is 1:9 and in the black head tube is 1:4.The blue-headed tube is often used for determinations of blood coagulation,and the black-headed tube is used for erythrocyte sedimentation rate.   EDTA The anticoagulation principle of EDTA is forming chelate with calcium ions in the blood to prevent blood coagulation such as EDTA-K2.The head of EDTA tubes are in purple.It normally used in blood routine examination, blood cell morphology examination.   Oxalate The anticoagulation principle is oxalate reacts with calcium ions to form calcium oxalate precipitation, thereby preventing blood coagulation. Such as sodium oxalate, ammonium oxalate, etc.The head of oxalate tubes are in gray.It is often mixed with sodium fluoride which can inhibit glucose glycolysis for blood glucose determination.   Heparin Heparin is a physiological anticoagulant which widely present in human tissues such as liver and lung. It takes effect by enhancing the activity of antithrombin III (AT-III), inactivating serine protease and preventing the formation of thrombin, such as lithium heparin, sodium heparin, etc.The head of heparin tubes are in green.It normally used in various biochemical tests.   In addition, Wuhan Desheng Biochemical Technology Co., Ltd. is a professional blood test reagents in research and development, production and sales. We are an established company specializing in the production of anticoagulant raw materials used in blood collection tubes, including sodium heparin, lithium heparin, dipotassium EDTA, tripotassium EDTA, disodium EDTA, potassium oxalate, trisodium citrate, sodium fluoride, etc.Welcome your consultation.

Anticoagulants are preparations added to the blood to prevent blood coagulation by inhibiting the synthesis or function of various coagulation factors exist in the blood. Anticoagulants are commonly used for conditions including deep vein thrombosis, pulmonary embolism, coronary thrombosis, and disseminated intravascular coagulation. The anticoagulant raw materials produced by Desheng mainly include sodium heparin, lithium heparin, ethylenediaminetetraacetate (dipotassium EDTA, tripotassium EDTA, disodium EDTA), which are mainly used in blood collection tubes to store blood.   Sodium heparin, lithium heparin are mainly used to promote the activity of antithrombin III, which inactivates thrombin to prevent blood clotting. The potency of heparin sodium and lithium heparin produced by our company is 150IU/mg, and the potency of anhydrous is 160IU/mg. It is mainly used for in vitro diagnosis and can be adjusted according to customer requirements. Injecting heparin sodium or heparin lithium into the blood collection tubes can be used for anticoagulation of blood samples for emergency biochemical, TORCH, and blood flow detection.   EDTA potassium salt anticoagulant is an amino polyhydroxy acid that can effectively conjugate calcium ions in blood to prevent blood coagulation. EDTA potassium anticoagulant has little effect on the coagulation of blood corpuscles and the morphology of blood cells. The EDTA dipotassium and EDTA tripotassium anticoagulants produced by our company are both used in vitro and cannot be used for injection. They have excellent properties and have a purity of over 99%. Add potassium salt of EDTA into the blood collection tubes, which can be used for general blood routine examination and blood ammonia detection, but cannot be used for blood coagulation and trace element examination.   With 17 years in research and production, Hubei New Desheng Material Technology Co.,ltd developed all kinds of blood collection tube additives like sodium heparin, lithium heparin, EDTA dipotassium,EDTA tripotassium,EDTA disodium.What we can provide is competitive price and good quality,welcome to inquiry.

Lithium heparin green tube is a blood collection tube for plasma collection in blood testing. Due to this kind of medical device has the effect of anti-coagulation, the plasma can be separated from the blood after blood collection.Except for the collection of plasma required for biochemical tests,it’s also used for subsequent cell culture experiments of blood cells such as lymphocytes after blood collection. However, this method cannot be used for the test items of white blood cell count and classification, which may lead to inaccurate test results. Lithium heparin blood collection tubes can mainly check liver diseases, such as viral hepatitis or liver cancer,liver abscesses and fatty livers. Lithium heparin is not a test items, but a anticoagulants.   With the effect of antithrombin,lithium heparin are added to the blood collection tube with the green cap,which can prolong the coagulation time of the specimen. It is suitable for red blood cell fragility test, blood gas analysis, hematocrit test, erythrocyte sedimentation rate and general energy biochemical determination, but not suitable for blood coagulation test. There is a 3ml tubes with lithium heparin green tubes which is often used for lead detection in children.Lithium heparin green tube is a heparin anticoagulant tube.Heparin sodium was used in the past may influence the result of electrolyte measurement. After technical improvement,lithium heparin is generally used. It can be applied for most biochemical tests, such as serum potassium.   Heparin anticoagulants are generally used for emergency laboratory tests, because they need to be centrifuged immediately after blood collection.The yellow or red test tubes need blood coagulation before centrifuging the serum, which will delay the emergency examination.In addition, the lithium heparin green tubes can also be used for trace element determination and blood flow experiments. The plasma separation tubes with light green cap, which is adding lithium heparin anticoagulant to the inert serum separation gel tube.This kind of tubes can separate plasma rapidly , and it is the best choice for electrolyte testing routine plasma biochemical testing and emergency plasma biochemical testing such as ICU. Plasma samples can be loaded directly on the machine and keep stable for 48 hours under refrigeration.   Heparin anticoagulation tubes are applied to check four kinds of blood coagulation. It is a common inspection item in the laboratory department,generally to maintain the natural form of red blood cells.If this situation is detected, some traditional Chinese medicine can be used for conservative treatment.   Hubei New Desheng Material Technology Co.,ltd is specialists for all kins of blood collection tube additives, which made from good quality of raw materials, welcome to inquity.

Most of tests in clinical chemistry, immunoassays are need to detect serum. After blood collection, it will coagulate naturally. Under the action of coagulation factors, fibrinogen is decomposed into fibrin filaments, which tightly surround blood cells to form blood clots, and a part of serum is precipitated.However, if the blood collection volume is insufficient, the precipitated serum cannot satisfy detection needs. Therefore, the serum separation gel produced to quickly and fully separate blood clots and serum or separate plasma from cells. The operation is simple and practical. Today, the editor of Desheng will briefly explain the problems that may occur in the use of serum separation gel,and our suggestions for them.   In practical operation, there will be various problems related to the separation glue, such as the generation of air bubbles in the blood collection tubes, and the phenomenon of separation glue drawn a wire when added into tubes. The reasons and solutions for these problems are analyzed below.   In the process of adding glue by machine or manually, the separation gel may contact with the air when it is injected into the bottom of the blood collection tube, resulting in the generation of air bubbles. Or the vacuum of the mixer is not enough, which will cause air to enter and form bubbles. This bubble will not affect the properties of separation gel. When bubbles appear, Desheng recommends centrifuging for 2 hours after adding glue. In addition, when the separation gel is sterilized by cobalt 60 irradiation, the temperature of the separation gel in the test tube can reach 80 °C. When the irradiation dose is too large, a great amount of heat is not discharged in time, and bubbles will also be formed. Desheng Company recommends that the irradiation dose should be controlled at 15-25kgy. The temperature of the serum separating glue in the PET tubes should be controlled at 40-50 °C, and the glass tubes should be controlled below 80 °C.   Serum separation gel is a viscous fluid, and its viscosity varies with temperature. When the ambient temperature is low, it will difficult to add glue, and cause wire drawn phenomenon. At that time,Desheng recommends heating the separating gel to around 60-70 ℃ by hot water to reduce the viscosity. Increase the suction speed or break the wire by vibration are also can solve the problem.   After years of research and development, Hubei New Desheng Material Technology Co., Ltd. has obtained an independent patent for serum separation gel. Cooperate with our company,we can provide you with more professional advices about serum separation gel. If necessary, please send inquire.

Today, Wuhan New Desheng Material Technology Co., Ltd. will introduce some common questions about the application of lithium heparin in blood collection tubes. FAQ 1: What does it check for blood collection tubes with lithium heparin? The normal applications of blood collection tubes with lithium heparin is blood rheology tests, blood cell volume tests and blood gas tests (Pls note: lithium heparin we produced are raw materials,it cannot do blood gas analysis). It also can be used for the detection after hemodialysis and other specific items such as arterial blood gas analysis, detection of electrolytes, calcium ions, etc. FAQ 2: What is the grade of lithium heparin applied in blood collection tubes? Lithium heparin applied in blood collection tubes need biochemical grade, like the powder we produced by Desheng. And the potency per milligram is greater than or equal to 150IU. FAQ 3: Do the blood collection tubes added with lithium heparin need to be dried? The blood collection tube added with lithium heparin must be completely dried, because lithium heparin is a mucopolysaccharide substance, which can easily breed bacteria in the tubes. FAQ 4: What is the normal operation after lithium heparin anti-coagulation tubes collecting blood samples? Under normal circumstances, the tubes with green cap is lithium heparin anti-coagulation tubes. In order to ensure sufficient blood anti-coagulation, it must be gently inverted and mixed 5 to 8 times as soon as possible after blood collection, otherwise the blood will coagulate. Vigorous can cause hemolysis with blood cells rupture. FAQ 5: Can lithium heparin be used with other blood collection tube additives? Lithium heparin can be used with sodium fluoride for blood glucose testing, and with serum separation gel for electrolyte testing,which is to check whether the content of electrolytes in the body is normal, mainly including potassium, sodium, calcium, magnesium, iron, phosphorus, etc. The activities and metabolism of biological cells must be carried out in a liquid state. Under normal circumstances, the fluctuation range of body fluids and components is small, so as to keep the volume, electrolyte, osmotic pressure, and pH of body fluids relatively stable. The above are answers for common questions that most people confuse about the application of lithium heparin in blood collection tubes. Hubei New Desheng Material Technology Co., Ltd. is a manufacturer for a series of blood collection tube additives. We have rich experience in R&D.Please feel free to inquire if you have any requirements.

Heparin sodium is a white or off-white powder with anticoagulant effect both in vivo and in vitro.It is odorless, easily soluble in water, and insoluble in organic solvents such as ethanol and acetone. It has a strong negative charge in aqueous solution and can combine with some cations to form molecular complexes. The solution of heparin sodium is relatively stable at PH 7.   There are many anti-coagulation mechanisms of heparin sodium applied in blood collection tubes, mainly by combining with antithrombin III (AT-III), inhibiting the action of coagulation factors, thereby preventing platelet aggregation and destruction, hindering the formation of thromboplastin, and preventing prothrombin from changing. It is thrombin, which prevents fibrinogen from becoming fibrin and exerts an anticoagulant effect.   Heparin sodium is often used in the collection and anti-coagulation of blood samples for clinical biochemical examinations and emergency biochemical examinations, and is also suitable for blood sample collection and anti-coagulation in some hemorheology projects.In addition to blood anti-coagulation, heparin sodium can also be used for drugs’ injection.   Heparin sodium is a mucopolysaccharide substance. After being prepared into a solution,it is easy to grow bacteria if it’s not used for a long time.Therefore, it should be used immediately after being prepared into a solution with deionized water or distilled water.Sealed and stored in a sterile state not exceed one week. Hubei New Desheng Material Technology Co., Ltd. recommends that the conventional dosage for disposable venous vacuum blood collection tubes is 5-20IU heparin sodium anti-coagulation with 1mL of blood , and 8-10IU heparin sodium anti-coagulation with 1ml blood for peripheral blood anti-coagulation. Heparin sodium on the market is generally extracted from small intestine of pigs with wide fresh supply source.The potency of heparin sodium produced by Desheng is 150IU/mg, and the anhydrous potency is 160IU/mg.The white powder obtained by refining and purification can maximize the accuracy of the experimental results.   The anti-coagulant effect is better if use heparin sodium and serum separation gel at the same time. The quality of the serum separation gel will affect the anti-coagulation effect of heparin sodium, so it is recommended to mix it with the anti-radiation separation gel produced by Desheng.

The full chemical name of MOPS is 3-morpholinepropanesulfonic acid. It is a white crystalline powder at room temperature with good hydrophilicity. 10g of MOPS powder can be completely dissolved in 100ml of water at 20°C, and the dissolved solution is colorless and transparent.MOPS is often prepared as a zwitterionic biological buffer to adjust the pH of the solution in biochemical reactions.   Specifications of MOPS: CAS No.:1132-61-2 Molecular Formula: C7H15NO4S Molecular Weight:209.3g/mol PH range:6.5-7.9 pKa(25℃)：7.0-7.4 Purity:>=99%   As a common buffer, MOPS buffer has a wide range of applications.Editor of Desheng will elaborate on several applications of MOPS buffers as following: 1. Since the pH range is between 6.5-7.9, MOPS buffer can be used to separate, purify, and extract RNA and protein, but cannot be used to separate DNA because it can interact with DNA and form complexes. 2. MOPS buffer can bind to iron, but does not react with most metals such as magnesium, manganese, cobalt, nickel, etc. Therefore,it is often added to stabilize the acidity of the solution in cell culture media that do not require iron ions, such as bacteria, charcoal yeast, and mammalian cells.It should be noted that the concentration of the buffer has a great influence on the PH of the solution, so when using the MOPS buffer to adjust the PH of the cell culture, the concentration of MOPS should be less than 20 mm. 3. In the non-denaturing agarose gel electrophoresis experiment of RNA, MOPS buffer is more suitable for stabilizing the pH value of the solution than other buffers. 4. Because the UV absorbance of MOPS buffer is very small, it does not interfere with the measurement of absorption during UV/Vis spectrophotometry. 5.At room temperature, the chemical properties of MOPS buffer are very stable. When it interacts with the peptide backbone of bovine serum albumin, it can promote the protein to reach a static stable state.   MOPS buffer has a strong buffering capacity in the pH range of 6.5-7.9. The point should be noticed is that MOPS can change the interaction between lipids, such as affecting the thickness and barrier properties of the rat endothelial surface layer, the mRNA expression form of bovine embryos produced in vitro, etc.It can be oxidized by strong acids and strong alkali.Therefore,these substances should be avoided in application. Hubei New Desheng Material Technology Co., Ltd. is a professional manufacturer of biological buffers. The production process is stable and the appearance of the product is pure white crystal powder.

Carbomer produced by Hubei New Desheng is white loose powder with strong hygroscopicity. Therefore, it must be stored in a plastic bag at a dry place . When we use carbomer, it is usually made into gel and added into raw materials of daily chemicals or medicals.   What Influence the Characteristic of Carbomer Gel? 1. Carbomer gel properties are influenced by pH value With a large number of free carboxyl groups, the pKa value of carbomer polymers are usually small. If the PH of the medium is less than 4, the carboxyl groups are rarely separated, and if the PH is greater than 4, the carboxyl groups begin to separate, the polymer dissolves, and the viscosity increases.When PH reached 8, it is basically completely separated and the viscosity is the largest. The PH value of the medium also affects the adhesion of carbomer gels. When the pH value is lower than pKa, the binding ability of the gel is strong, and the adhesion will increase. At the same time, the ionic strength of the medium can change the sensitivity of the carbomer gel to pH value. When the ionic strength is high, the carbomer releases protons and decrease its pKa value, so it can be dissolved at a lower PH value.   2. Carbomer gel properties are influenced by ionic strength In some drugs, the effect of the drug on the PH and ionic strength of the medium around the gel cannot be ignored. The acidity of the drug also affects the properties of the gel, so the effect of acidic drugs is more pronounced.   3. Carbomer gel properties are influenced by other excipients The simultaneous use of polyvinylpyrrolidine and polyoxyethylene as auxiliary agents with carbomer gels can reduce the mucoadhesion of carbomer gels. The degree of reduction is related to the concentration and molecular weight of coexisting excipients. The high concentration over 5% of excipients can greatly reduce the adhesion of carbomer gel, and if the concentration is reduced to 0.5%, the effect is small. Generally, the PH value of the medium does not change this property of polyvinylpyrrole and polyoxyethylene. Magnesium stearate is hydrophobic,which also reduces the adhesion of carbomer gels.   Above is the detailed introduction of Hubei New Desheng Material Technology Co., Ltd. on the factors that affect the properties of carbomer gel. Hubei New Desheng Material Technology Co., Ltd. is a manufacturer specializing in the production of raw materials for biochemical testing and detection reagents, including carbomer 940 and 980 with chemical level.

What is serum separation gel? It is a viscous fluid and an inert high molecular polymer. Its structure contains a large number of hydrogen bonds which associated with a net structure. Serum separation gel is a mixture of high molecular polymers, which are polymerized from a variety of monomers with different molecular weights. Due to its relatively large molecular weight, its appearance like gel.   The principle of serum separation gel to separate serum and blood clots: Serum separation gel is a substance used to separate serum from coagulated blood or divide plasma from cells.It forms a separation layer between the cellular components of blood and serum, which can effectively prevent the exchange of substances between blood cells and serum,and ensure the stability of serum components within a certain period of time.   First of all, serum separation gel can separate serum and blood clots because its thixotropic characteristic.With thixotropic,the net structure of serum separation gel is destroyed and becomes a fluid with low viscosity under the action of centrifugal force.When the centrifugal force disappears, the network structure is re-formed and return to a high viscosity fluid.   Therefore, under the action of thrombin, blood will form serum and blood clots. And under the action of centrifugal force, the separation gel become liquid and moves upward, preventing the material exchange between the serum and the blood clot.Then, the reason of serum separation gel can separate serum and blood clots is the specific gravity of serum separation gel is between 1.045-1.065, the blood clot is about 1.092g/ml, and the serum is about 1.025-1.030g/ml.The specific gravity of serum separation gel is in the middle, so it can isolate in the fully solidified state.After serum and clot are quickly centrifuged,high-quality samples will get to be shipped and transferred.   Hubei New Desheng Material Technology Co., Ltd. is a manufacturer specializing in the research and development of serum separation gel. We have our own patent with high quality serum separation gel.If you have any requirements,pls call for consultation.

Hubei New Desheng Material Technology Co., Ltd. is a professional manufacturer of raw materials for biological buffer.The biological buffer produced by our company are stable with high purity.It can be used in common skin care products and cosmetics such as toner, essence, lotion, eye cream and face cream middle. Here are three buffers commonly used in cosmetic raw materials, 3(-hydroxymethyl)aminomethane (Tris), 4-hydroxyethylpiperazineethanesulfonic acid (HEPES),and bis(2-hydroxyethyl)idene Amino tris (hydroxymethyl) methane (Bis-Tris). TRIS 3(-Hydroxymethyl)aminomethane (TRIS), also known as tromethamine, is a zwitterionic biological buffer. In the PH range of 7.2-9.0, TRIS has the best buffering ability, and can maintain the PH value of the solution for a period of time at 4.75-5.75 that is just suitable for human skin. Therefore, TRIS buffers are often used in emulsifiers, thickeners, moisturizers and other formulations to adjust and stabilize the acidity and alkalinity of products. Because TRIS buffers can reduce or suppress products’ odor, they can be used in the formulation of sunscreens, leave-in nail polishes, eye makeup and lotions. HEPES Like TRIS, 4-Hydroxyethylpiperazineethanesulfonic acid (HEPES) is also a zwitterionic buffer with a suitable pH range of 6.8-8.2. HEPES buffer is often used to adjust the PH value of cosmetic products, stabilize it in a weakly acidic state that is suitable for human skin.It does not affect the efficacy of other ingredients, and even promotes the transdermal absorption of its functional ingredients. The concentration of the buffer affects its buffering capability,a certain concentration of HEPES can be used in exfoliating products. Bis-Tris Bis (2-hydroxyethyl) imino tris (hydroxymethyl) methane (Bis-Tris) is a weakly acidic buffer containing trace ionized hydrogen ions. In raw materials of cosmetics, Bis-Tris can adjust the PH value of the product and keep it stable in a suitable acid state. Bis-tris buffer has excellent decontamination, dispersing, emulsifying, anti-static ability, and high ultraviolet absorption ability, so it is often used to replace maleic acid in some sunscreens. The TRIS, HEPES and BIS-TRIS produced by our company are white crystalline powder with excellent properties.The purity can reach more than 99%. Professional R&D team can customize indicators according to your requirements, welcome to consult.

In biochemical tests, it is often seen that the serum in the upper layer of the blood collection tube with serum separating gel is red after being centrifuged. Which is the rupture of blood cells in the test tube and the escape of hemoglobin. Outside the human body, if the RBC (red blood cells) are in a solution with too low osmotic pressure, water enters the red blood cells, causing swelling and rupture, resulting in hemolysis. Hemolysis in the human body is mainly due to the inherent defects of red blood cells, or due to the presence of auto antibodies, chemicals, snake venoms and other factors in plasma, causing excessive destruction of RBC. So why does hemolysis occur in a test tube containing serum separation gel?   First, let's understand the principle of separating serum and blood clot with separating gel. After the blood sample is put into the test tube, under the action of thrombin factor, fibrinogen is converted into insoluble fibrin filaments which encircled the blood cells to form blood clots and precipitate a part of serum,that is natural coagulate which is difficult to fully coagulate.With characteristic of thixotropy , the separating gel in the tube becomes liquid and flows under the action of centrifugal force. Due to the specific gravity, the blood clot with higher specific gravity settles in the bottom, the lower serum is in the upper layer, and the separating gel is in the middle. After the centrifugal force disappears, the separating gel becomes gel and completely separates the blood clot from the serum. Separating gel is inert, it does not react with anything in the chemical reaction. So it does not change the products of the reaction, nor does it destroy the hemoglobin in the cells. From this point, serum separation gel is not the cause of the destruction of blood cells.   What Should Be Notice When Using Serum Separation Gel 1. Disinfect with iodine, the alcohol in the iodine is not dry and enters the blood collection tube to cause pollution and destroy red blood cells; 2. Blood collection, if the blood collection volume is insufficient and the pressure is too large, the RBC in the tube will rupture, which cause hemolysis; 3. Transfer the sample to the blood collection tube with a blood collection needle,the blood cells were damaged due to the action of pressure; 4. Invert and mix the blood collection tube about 5 times. If the force is too large, the blood cells will rupture; 5. Centrifuge the sample blood before it has fully reached the time of coagulation.

Vacuum lancets are mainly used for blood collection and preservation. It is composed of vacuum blood collection tube,needle (including straight needle and scalp blood collection needle), needle holder and blood collection tube additives, which are used to meet multiple comprehensive blood tests in clinical practice. Different blood collection tube additives are used in different biochemical and immune and other clinical medical tests. According to the different additives of blood collection tubes, vacuum blood collection tubes are generally divided into three types, anti-coagulant,anticoagulant,and serum separation gel blood collection tubes.   Anti-anticoagulant Blood Collection Tubes Different anticoagulants are added to the blood collection tubes for specific test items .An anticoagulant tube filled with heparin sodium is used for blood gas analysis, hematocrit test, erythrocyte sedimentation rate and general energy biochemical determination, and red blood cell fragility test.For plasma separation and testing, electrolyte testing,then blood collection tube with Desheng’s serum separation gel and heparin Lithium.EDTA anticoagulant tubes are used for general hematology tests.For blood sugar testing,anticoagulant tubes containing potassium oxalate or sodium fluoride are used.   Coagulant blood collection tubes For coagulant blood collection tubes,silicone oil sprayed over the wall to prevent hanging,and coagulant reagent is added.Coagulant reagent can activate fibrin protease which turn soluble fibrin into insoluble fibrin aggregates, and then form stable fibrin clots. Rapid blood coagulation with physical reaction,no need other heating facilities.After the blood collection is completed,put the tubes straight for 15 minutes and then centrifuge under 16℃. Which can make high-purity serum can be obtained for general emergency biochemistry.   Blood collection tubes with serum separating gel It’s a kind of blood collection tubes containing serum separating gel and coagulant. The tube wall is siliconized and coated with coagulant to accelerate blood coagulation and shorten the test time. The separation gel in the tube has a good affinity with the PET tube and plays an isolation role. Generally, even on a common centrifuge, the separation gel can completely separate and accumulate the liquid components (serum) and solid components (blood cells) in the blood. And form a barrier in the test tube. No oil droplets are produced in the serum after centrifugal to clog the machine.Blood collection tubes with serum separation gel are mainly used for serum biochemistry (liver function, kidney function, myocardial enzyme, amylase, etc.), electrolytes (serum potassium, sodium, chloride, calcium, phosphorus, etc.), thyroid function, drug testing, AIDS testing, tumor markers, serum immunity study.   Hubei New Desheng Material Technology Co., Ltd is a professional manufacturer of blood collection tube additives.
