Dark green lithium heparin tube       As a natural ideal anticoagulant, heparin lithium is often added to dark green test tubes to prevent blood coagulation. Generally, the quality of heparin lithium is determined by its potency. The common potencies are 150IU, 160IU, 170IU and 180IU. The higher the potency, the higher the quality and price of heparin lithium will be. Next, we will introduce the application of dark green lithium heparin tube and the precautions for use.  

Recently, Desheng has been receiving inquiry about heparin sodium, and the quote is too different from the market. It is normal to have such emotions, because the price of heparin sodium is related to type and quality. Let me introduce the price of heparin sodium in detail below.   Heparin was mainly extracted from animal organs in the early days, and later research found that some mammalian organs also contained heparin, so it was derived from pig intestines, cattle and sheep and other organs. It has a wide range of uses, such as anticoagulant in blood collection tubes and various thrombotic drugs, etc. The production process of heparin varies from manufacturers, so the use and cost are different, and the price will also be vary naturally.   Different types of heparin sodium 1. Unfractionated heparin sodium: a mixture composed of some chemical substances alternately, usually extracted from pig intestines or bovine lungs, and prepared into drugs for clinical use. Because it is a kind of drug, the price will be higher. 2. Crude heparin sodium is extraction from pig intestines.With elution, filtration, merging of the supernatant and filtrate.Then adding ethanol for precipitation.After carefully drying and sucking out the supernatant, collecting the lower sediment, pumping filter until dry, and then vacuum-dry to produce crude heparin. The requirements and production process of this heparin sodium are relatively low, and its price is also lower. 3. Vacuum blood collection tube anticoagulant heparin sodium.It is mainly used as an additive in vacuum test tubes. As an anticoagulant tube, it can prevent blood samples from coagulating within a certain period of time. This kind of heparin is different from other types and has a relatively high potency. For high-quality heparin sodium, the price gap will be larger.   Differences in origin of heparin sodium For the heparin used in the medical industry, some manufacturers use imported raw materials, and some use domestic raw materials. The difference between imported and domestic products naturally leads to price differences.   Rare sources of heparin Although heparin can be extracted from the organs of mammals such as pigs, cattle, and sheep, these heparins are mainly crude products, and the key extraction site is the small intestine of pigs, but the heparin extracted from pig intestines is very rare, sometimes 3000 pigs can extract 1 kg of heparin. If the pork price fluctuates and adjusts, the price of heparin sodium will also be affected. Therefore, the price adjustment of heparin sodium is related to various factors.   Desheng is a Chinese manufacturer specializing in the production of heparin sodium, which is mainly added to vacuum test tubes for in vitro anticoagulation. The price can be negotiated according to the quantity, and can be customized according to the different needs of customers.If you have any requirements in this regard, welcome to click on the website for consultation!

Can heparin sodium anticoagulant tube do blood routine?       In recent years, the export volume of heparin sodium products has been rising, and sometimes the market will be in short supply, resulting in price fluctuations. At the same time, heparin sodium products are also favored by the medical industry. It can not only be added to test tubes, but also be prepared into drugs. It has a special role in reducing blood lipids and treating thrombotic diseases.       In these applications, the use of anticoagulants added to blood collection vessels is relatively high, which not only provides strong support for emergency biochemical examination, but also further ensures the accuracy of the test results. Since it is widely used in clinic, can it be used for blood routine examination? Let's give you a detailed introduction.       Production of heparin sodium       It was found in the early stage that heparin sodium is a substance that exists in the internal organs of animals. However, due to the different use methods and production processes in different countries, its main source of extraction is also different. Generally, the main source of production in foreign countries is the lungs of cattle and sheep, while the main source of production in China is in the intestines of pigs.       Application of heparin sodium       As an important substance in the preparation of drugs, it can be used to prevent and treat myocardial and thrombotic diseases, and effectively prevent the blockage of blood vessels and the expansion of thrombus in patients. In addition, it is also an in vitro anticoagulant commonly used in test tubes. It is generally used in biochemical tests and plasma biochemical tests, not in blood routine tests.       Reasons why heparin sodium is not used for routine blood test       Blood routine test is one of the most commonly tested items in clinical practice. Medical staff often use blood to determine whether the patient has infection or platelet disease in the body. The whole process depends on coagulation factors to play its role, and it is also checked through four items of coagulation. Generally, they will choose to use EDTA anticoagulant tubes instead of heparin sodium anticoagulant.       In addition, heparin sodium has its own unique anticoagulant characteristics, which will affect the whole coagulation process. The consequence of using it may be platelet damage. The accuracy of platelet data cannot be guaranteed in routine blood testing, so generally, heparin sodium anticoagulant tube will not be used and EDTA anticoagulant tube will be used.       Desheng is a Chinese manufacturer of blood collection additives, with complete product types, which can meet customers' one-stop purchase, and is authoritative. The products meet the quality requirements of ISO9001. At the same time, the company has set up a after-sales team and a technical research and development team to ensure that the service and quality are trusted by customers.

How much is the price of heparin sodium per kilogram?       Recently, some people in the market have been asking about the price of heparin sodium. Desheng, as a manufacturer, has also heard from customers that "the price difference of heparin sodium is too big". In fact, the price difference is very normal. Because its price is affected by many external factors, such as type, output and potency, which are the key to determine the price, how much is it per kilogram? Let's give you a detailed introduction.       If you want to know the specific price of one kilogram, you need to look at it from different aspects. The technology of producing heparin sodium varies from manufacturer to manufacturer, and the natural price will also be adjusted according to the actual situation. The main factors affecting the kilogram price of heparin sodium are as follows:       1、 The type difference of heparin determines the price       There are various types of heparin on the market, which are mainly divided into ordinary heparin, low molecular weight heparin and vacuum anticoagulant heparin. Generally, ordinary heparin and low-molecular-weight heparin are often prepared into drugs for human treatment or injection. The production requirements and product quality control are very strict. The price per kilogram is several times higher than that of other heparin.       The heparin sodium used in vacuum blood collection is generally lower than the heparin injected into human body because it is used in vitro, but this does not mean that the price is low. It will determine the price of kg according to the potency.       2、 The raw material and potency of heparin sodium determine the price       Because many manufacturers use different raw materials, their prices will also vary greatly, such as imported and domestic. If the purchase manufacturer uses imported materials, its selling price will naturally increase as a whole. In addition, potency is also a decisive factor in the price of heparin sodium. Most manufacturers also sell heparin sodium based on potency. The higher the potency is, the more expensive the price is. At present, the potency of Desheng is between 150IU-180IU.       3、 The extraction of heparin sodium determines the price       In the early stage, it was mainly extracted from animal liver organs, and then gradually extended to the key part of pig small intestine. Through data research, it is found that only 3000 pigs can extract 1 kg of heparin to prepare heparin sodium, and the price of pork is subject to market fluctuations. Once adjusted, the price of heparin sodium in kg will also be affected.       The price of 1kg of heparin sodium is greatly influenced by the outside world. You can't just refer to one manufacturer, and don't think that the high price is the problem of the manufacturer. You can investigate it from the above aspects. Desheng is a manufacturer specializing in producing heparin sodium in China, which is mainly used as an anticoagulant in vitro in blood collection. The price can be ordered according to different needs of customers. If you have relevant requirements, please click the website for consultation!

Are heparin sodium and heparin lithium tubes interchangeable?       As commonly used test tubes in medicine, heparin lithium and heparin sodium tubes are welcomed by major medical institutions because they can prevent blood coagulation, and also play an extremely important role in clinical testing. From the appearance, the raw materials of both are white powder. When added to the blood collection tube, they are also prepared into transparent and odorless solution. Therefore, many people will think that heparin sodium and heparin lithium are the same substance, which can be interchanged when added to the test tube. In fact, heparin sodium and heparin lithium are fundamentally different and cannot be interchanged. Let me give you a detailed analysis.       1、 Difference of binding ions       In terms of application, although both of them can prevent blood clotting and are both used as a binding form of heparin, there are differences in their effective binding ions. Generally speaking, heparin lithium is converted through the preparation of heparin sodium, so it looks similar in appearance, but different in texture. Interchange during use may cause unstable detection performance.       2、 Different dosage of heparin sodium and heparin lithium tube       Although both are additives in vacuum test tubes, there are great differences in the amount of the two additives in the industry standards. For example, the standard of heparin lithium is 9.41-281U/ml, and the standard of heparin sodium is 121U-301U/ml of blood. If the blood collection vessel requires 1 liter of blood, the corresponding added dose is also different. Once the dose is not matched, the concentration in the tube will be too high or too low, leading to deviation in the results.       3、 Differences in white blood cell count results       Through experimental research, it was found that even under the same sample requirements, the white blood cell count results detected by heparin sodium and heparin lithium tubes were different. With the extension of time, heparin sodium will be more regular, and the white blood cell count will also increase slowly and then decrease, but the measured value of heparin lithium will decrease slightly, which is relatively slow and stable. If used interchangeably, it will interfere with the final detection results.       Desheng, as a supplier of additives for blood collection in China, not only produces heparin sodium and heparin lithium, but also includes commonly used anticoagulants such as EDTA, EDTA, sodium citrate, etc., which can meet different needs of customers.

How to use heparin sodium as anticoagulant       As a natural anticoagulant in mammals, heparin has a wide range of applications, whether in clinical medicine or cosmetics, or in drug preparation. As a natural ideal anticoagulant, it has naturally attracted the attention of all countries in the world and has gradually become one of the main raw materials exported by China. So, since heparin sodium is so popular, how is it used as an anticoagulant? Let's give you a detailed introduction.       When it comes to how to use it as an anticoagulant, it is actually inseparable from its extraction method and production process. At present, the main source of heparin sodium is from pig intestines, with high content. The domestic pig industry is developed and can supply heparin to the maximum extent. Then the extracted heparin is purified to prepare the required heparin sodium.       As an anticoagulant, the preparation process of heparin sodium has the following steps:        1. Raw material treatment: clean the extracted fresh pig intestines, scrape the mucous membrane, and then put them into a blender for mixing and standby.       2. Heating enzymolysis: at this time, put the stirred intestinal mucosa into a heating vessel and add water to mix and stir, then add trypsin and weak alkaline solution in turn, fully adjust the ph value until the solution ph reaches 8-10, and then continue heating, and when heating to a certain time and temperature, filter to obtain the filtrate.       3. Cooling and adsorption: cool the filtrate obtained, remove the floating oil on the upper layer after cooling, and then add resin to stir for adsorption for about 6 hours. After adsorption, filter out the resin.       4. Elution: put the collected resin into the elutor for washing, add a certain proportion of sodium chloride solution, keep the temperature at about 50 ℃, and mix for 3 hours before collecting the eluent.       5. Sedimentation: filter the obtained eluate, then put it into the appliance, add alcohol and stir to adjust the ph value evenly, the range should be kept at 7-8, leave it for about 10 hours, seal and precipitate, then filter the precipitate, and use it for standby.       6. Dehydration and drying: put the sediment into a drying oven to dry, and then add heparin sodium into the test tube as an anticoagulant, and then add it as a solution.       The above is the introduction of how heparin sodium can be used as an anticoagulant. Its manufacturing process is the key to determine the quality of anticoagulant, so special attention should be paid to the details in the production process. Desheng, as a manufacturer of heparin sodium in China, has stable production process and simple method. It will not affect the process of the experiment when used as an anticoagulant in vitro.

What are the types of heparin sodium?   As an anticoagulant, heparin sodium is naturally existing and is mainly extracted from the liver of mammals. Because of its special properties, it can affect the coagulation process, so it is widely used for anticoagulation in vivo and in vitro. For those who fully understand it, the types of heparin sodium are very clear, and different quotations can be obtained according to the types, but those who do not understand it will lose in price. In order to avoid these unnecessary losses, the following details are given to everyone Let me introduce the types of heparin sodium, so as to distinguish the purchase.   1. Crude Heparin Sodium This kind of heparin sodium is extracted from pig intestinal mucosa, and it is generally manufactured through artificial processing. The process is simple, its numerical value is not high, and its appearance is yellow powder. Raw materials for series products.   2. AR grade heparin sodium It is mainly extracted from pig small intestine mucosa, but the processing technology is more refined, and the key values are strictly required. The appearance is white powder, easily soluble in water, and has strong anticoagulant activity. The blood collection tube is used as an extracorporeal blood anticoagulant.   3. Injection grade heparin sodium The injection grade is directly used in the human body, and the production process is more stringent. Not only are the requirements high, but the price is also high. It is one of the important injection drug raw materials for the prevention and treatment of thrombosis and embolism, and has great clinical value. At the same time, it can also be prepared into medicine, which has the functions of anti-hemorrhage, blood lipid regulation and anti-inflammation. It will be used as the main medicine for treating disseminated intravascular coagulation, pulmonary heart disease, myocardial infarction and other diseases in clinical practice.   The above are the three main types of heparin sodium. The production process and requirements of different types are different, and the price is also fundamentally different, so everyone needs to pay attention to distinguishing them. As the main manufacturer of heparin sodium in China, Desheng sells products of external use grade, which are mainly added to blood collection tubes as in vitro blood anticoagulants, rather than directly used in the human body. Everyone should be aware of this . Due to the high requirements for heparin sodium added to the test tube, Desheng has equipped a professional team for research and development and testing to ensure that customers can use it with peace of mind. It also has an independent warehouse with sufficient goods and can provide it in large quantities. If you have relevant intentions, welcome to click the website to consult details!

In recent years, the development and use of anticoagulants has not only effectively improved the detection efficiency, but also provided guarantee for the detection results of patients. As one of the types of anticoagulants, heparin sodium is also favored by everyone. Why do you say that? In fact, this is still inseparable from its mechanism of action and use.   Use of Heparin Sodium It can be used clinically and in cosmetics. It is used as an anticoagulant drug and an in vitro anticoagulant in clinical medicine, especially as an in vitro anticoagulant in blood collection tubes. It can quickly process blood samples, improve detection efficiency and promote the accuracy of detection result. In the field of cosmetics, low-molecular-weight heparin sodium is generally added to creams, which can effectively increase the permeability of the skin, and can resist allergies and inflammation.   The mechanism of action of heparin sodium When it comes to the mechanism of anticoagulation, it is mainly the heparin that makes effect. It is strongly acidic and is a natural anticoagulant that exists outside the body of mammals. It can delay blood coagulation in blood collection tubes. Through the following steps: 1. Control the activity and reaction of thrombin, so that prothrombin will not be converted into thrombin at the source. 2. In the case of high concentration, it can quickly interfere with the activity of thrombin and other blood coagulation factors, making them lower, preventing fibrinogen from changing into fibrin to a certain extent. 3. PLT is an important component in the blood system of the body. The performance of heparin sodium can hinder the aggregation and adhesion of PLT, and prevent the formation of coagulation, so as to achieve the anticoagulant effect.   Requirements for using heparin sodium First of all, as an anticoagulant for blood collection tubes, high-quality heparin needs to be used. After refining and purification, it can be formulated into a solution and added to the test tube. Because the crude product and the purified heparin sodium have many key numerical indicators different, using the crude product may lead to inaccurate test results. And when it is added into the test tube, it should be noted that the conventional dosage is 1mL of blood corresponding to 20IU of heparin sodium, so as to achieve the best effect of anticoagulation.   Desheng is a professional manufacturer of blood collection tube additives in China. The heparin sodium and heparin lithium produced are all added to blood collection tubes for in vitro anticoagulant use. Everyone needs to be aware of this. Desheng's blood collection tube additives are very popular and well received in the domestic market, and they have gradually expanded overseas. At present, they have cooperated with hundreds of overseas customers, which can meet the needs of different customers and supply in large quantities.

After continuous research, heparin sodium has occupied a place in the market as a natural anticoagulant substance, and many manufacturers have also invested in the production of heparin sodium one after another. But it’s not that there are more manufacturers, purchasing heparin sodium is a simple matter. During the procurement process, you will find that either the quality of heparin sodium is problematic or the price is too high. So next, I will introduce to you in detail how to buy heparin sodium and the issues that need to be paid attention to during the purchase process.   1. The manufacturer is the first choice Generally, whether the product is cheap or not has a lot to do with the merchant. When purchasing, you should try to choose factory direct sales to reduce the problem of middlemen earning the price difference. Moreover, the manufacturer has the advantage of independent research and development. Even if there are quality problems, they can be resolved immediately.   2. Stock supply I believe that after consulting with many parties, buyers will find that most merchants do not have stock , and there may even be orders or advance reservations. In addition, some manufacturers' production equipment and production processes are not mature enough, and their production capacity cannot keep up. Goods are in short supply. Therefore, you need to fully consult the quantity of goods and delivery time when purchasing. If the manufacturer can deliver the goods on the same day or the next day, you can basically purchase as the target manufacturer.   3. Quality of Heparin Sodium As an in vitro anticoagulant commonly used in clinical practice, heparin sodium has higher requirements. It must ensure stable product quality and performance. The produced powder does not contain impurities. It is configured into a solution with high solubility and good transparency, so there is no need to worry about adding it to the test tube. . When purchasing, you can first request a sample test or issue a test report, and then purchase after meeting the requirements.   4. Service quality It is impossible to guarantee 100% no problems when buying any product. The most important thing is to have a perfect after-sales service, so that even if there is a problem, it can be solved immediately, and everyone can use it with peace of mind. Therefore, when consulting, you can check the service attitude of the other party and focus on asking whether after-sales service is provided, and whether there is a refund or exchange if there is a problem with the product.   5. Reasonable price Price is closely related to product quality. Generally, the price of high-quality products will naturally be high, but this also depends on whether it is a manufacturer or a middleman. Manufacturers usually adjust prices in order to improve their reputation and produce and sell products themselves, but middlemen will not take risks and will increase prices if they blindly sell. Therefore, when buying, you need to focus on whether the other party is a manufacturer or a middleman, as well as the value of the product itself, so that you can get an accurate quotation. Desheng is a Chinese manufacturer of heparin sodium. It is equipped with a professional R&D team. It is self-produced and sold without any third-party sales. The product quality can only be shipped after layers of testing and control by technicians. If you have relevant needs, please click on the website consult!    

How to measure heparin sodium As an anticoagulant substance, heparin sodium usually has a greater anticoagulant effect after being formulated into a solution, but sometimes it cannot be added at will, and heparin sodium needs to be determined according to the calculation formula to ensure the accuracy of dosage sex. According to the experimental requirements, the adsorption rate, absorbance, solution concentration and titer of heparin sodium are generally measured. The following will focus on introducing it to you.   1. Determination of the adsorption rate of heparin sodium The potency of the heparin sodium solution after adsorption is detected after a certain interval of time, and the total potency remaining in the solution is calculated at the same time, and the adsorption capacity is characterized by the total potency remaining. The titer of heparin sodium solution determined before adsorption was set as D0, and the titer of the experimental solution determined after adsorption was set as D1. (D0-D1) is the D value of resin-adsorbed heparin sodium. The average value of three parallel experiments is taken, and the determination formula is M=(D0-D1)/D0.   2. Determination of absorbance of heparin sodium Determination of the absorbance value of heparin sodium can adopt ultraviolet spectrophotometer, when the monochromatic light radiation passes through the measured substance solution, it is directly proportional to the amount absorbed by the substance and the thickness and concentration of the liquid layer, and its determination formula is A=lg(1 /T)=E×C×L.   3. Determination of the concentration of heparin sodium solution Prepare the test solution and the control sample solution during the preparation process. The amount of the tested components contained in the reference solution should be 100% ± 10%, and the reagents used should be consistent. Measure the test solution and the reference substance at the specified wavelength. After measuring the absorbance of the solution, the concentration of the solution can be calculated according to the determination formula.   4. Determination of Heparin Sodium Potency Usually, the sheep plasma method is used for determination. The water temperature is adjusted to about 37 degrees, and the frozen sheep plasma is taken out, melted and filtered, and set aside. Then two groups of test tubes with different ul were taken respectively, and 8% sodium citrate solution, 0.25% calcium chloride and filtered sheep plasma were added into the tubes. Cover the test tube, invert and mix slowly 3-4 times to make the inner wall wet, put it vertically in a water bath with a constant temperature of 37°C, take out the test tube after 1 hour, check the degree of coagulation, and record and calculate.   Desheng is a manufacturer of heparin sodium in China. It can provide professional testing reports. The potency of heparin sodium for different purposes can be customized according to customer requirements, and it is equipped with one-to-one after-sales service. Any problems will be solved immediately to ensure customer purchase experience. . If you have relevant needs, welcome to click on the website or call for details!

How to use heparin sodium       As a naturally occurring anticoagulant, heparin sodium is hidden in the liver organs of mammals, such as cattle, sheep and pigs, and then prepared into anticoagulants in vitro, which is conducive to reducing the blood coagulation ability and preventing the formation of harmful clots in blood vessels, so it is favored by various medical institutions, and its application field is gradually extensive.       However, it should be noted that heparin sodium has its own use methods and requirements. If you do not know how to use it, it is likely to lead to poor anticoagulation effect and deviation in the test results. So let's introduce how to use heparin sodium in detail. You can also pay attention to it when using it.       1. As an anticoagulant for blood in vitro, crude heparin cannot be used directly. The refined heparin sodium needs to be used to ensure the purity of the appearance color. It is dissolved in water to prepare a solution and then directly sprayed on the inner wall of the test tube. The conventional dosage of 1 ml of blood corresponds to 20 IU of heparin sodium.       2. Use after adding solvent to test tube γ Irradiation sterilization is carried out by irradiation with a dose of 8-25 kGy. Generally, the irradiation dose can also be determined according to the initial number of colonies.       3. Heparin sodium can be used at the same time with serum separation gel, and its anticoagulation and centrifugation effects can reach the best state, which is conducive to more accurate detection results.       4. When using heparin sodium anticoagulant tube, the blood sample should be inverted and mixed for at least 8 times as soon as possible after being collected, especially when the ambient temperature of blood collection is too high, if the mixing is not timely, half of the coagulation and half of the non-coagulation phenomenon will occur, pay attention to the use of shaking should not be too strong, just gently inverted.       5. When heparin sodium is used for anticoagulation, because it can participate in cell metabolism, the amount of heparin sodium used will interfere with the test results, so the amount of heparin sodium used should fully ensure the complete anticoagulation of the sample, so as to ensure the accuracy of the value.       The above five aspects briefly introduce how to use heparin sodium and the points for attention. As an anticoagulant in vitro, its requirements must be stricter. Knowing how to use it can effectively avoid problems in the results.       Desheng, as an old brand manufacturer of blood collection additives in China, has not only rich experience and strong strength, but also has always implemented the standard of "strict control" in product quality, and domestic enterprises that have cooperated with it have been praised in succession. At the same time, because it is directly supplied by the manufacturer, a large independent warehouse has been set up to meet a large number of customers' needs, and there is no shortage of goods.

What is the price of EDTA tri-potassium?       In recent years, with the progress of medicine, in order to save time and improve efficiency, many hospitals will generally use some reagents to assist in the detection, such as EDTA tri-potassium, which is frequently used in vacuum blood collection as an anticoagulant in vitro. Due to the increase in demand, the price of EDTA tri-potassium produced by various manufacturers in the market is rising. Many customers will pay special attention to the price. So, let's introduce it to you in detail.       Desheng has also received many calls from customers recently, all of which are sighing that "our price is cheaper than that of other manufacturers" and "the delivery speed is also very efficient". However, it is not that the price of Desheng Desheng has changed, but that of other manufacturers in the market has increased.       As the manufacturer of EDTA potassium trioxide, Desheng has always followed the principle of customer first in terms of price. As long as the price range of raw materials is not large, the price we give customers will not change easily. If it is a long-term customer, it will also enjoy additional preferential prices. So many people will basically choose Desheng after asking the price in the market. In addition, the company will provide sample tests to save customers the time to choose to buy.       So, what is the price of EDTA tri-potassium? In fact, this may ask different manufacturers, and the answer is completely different. Because there are many manufacturers of EDTA tri-potassium, but few of them produce dihydrate, and if equipped with professional technical teams, it is rare. So there will be many "manufacturers" with slogans on the market, but they are actually traders. It is not that the traders are not good, but that the traders will make different quotations on cost accounting. Most of the prices will be on the high side, and the manufacturers will have some advantages and lower prices.       How much is the price of Tri-potassium EDTA in Desheng? In fact, Desheng advocates batch quotation, just like the price of buying a thing is different from the price of bulk purchase. The price will be high if you order a small amount, but the goods above the ton level will give customers a favorable price. Of course, it should be noted that the products under the same level, EDTA tripotassium, have pharmaceutical level and industrial level, and the prices of these two levels are also different. When you are consulting, you should express your needs clearly so that you can get more accurate quotations. If you have any need for EDTA potassium salt, please click the website or call to purchase!
