Introduction to ethylenediaminetetraacetic acid dipotassium salt dihydrate
Due to the fact that medical staff analyze patients' conditions based on abnormalities in various blood indicators, blood sample testing has become one of the important and necessary procedures in clinical practice. The early collection and analysis of blood samples were all manually operated, and later gradually developed into fully automated operations. As a blood processing reagent, the application of ethylene diamine tetraacetic acid dipotassium salt dihydrate also promoted the development of automated blood testing.
1、 The Effect of Ethylenediaminetetraacetic Acid Dipotassium Salt Dihydrate
There is often a difference between ethylenediamine tetraacetic acid dipotassium salt and ethylenediamine tetraacetic acid dipotassium salt dihydrate in the market. As an anticoagulant reagent in blood collection, the advantage of dihydrate will be very obvious. Because it contains two water of crystallization, compared with the anhydrous dipotassium EDTA, it has weaker moisture absorption capacity, stronger stability, is not easily affected by moisture, and is conducive to storage and use.

2、 Anticoagulant principle of ethylenediaminetetraacetic acid dipotassium salt dihydrate
As a popular anticoagulant reagent, its demand is increasing. The principle of action is that it is an amino polycarboxylic acid that can be close to calcium in blood samples. When complexed with calcium, prothrombin cannot be converted into thrombin and has minimal impact on blood cell components, thus achieving anticoagulant purposes. Generally, 4 ℓ of ethylenediaminetetraacetic acid dipotassium salt dihydrate corresponds to 2 milliliters of anticoagulant blood, but it must be a dihydrate with a purity of over 99%, otherwise the test results may be inaccurate.
3、 Addition and use of ethylenediaminetetraacetic acid dipotassium salt dihydrate
Due to the powdery nature of the produced ethylenediaminetetraacetic acid dipotassium salt dihydrate, it needs to be prepared into a solution when added to a test tube. Deionized water is often used to dissolve and mix, and then the solution is sprayed onto the tube wall by machine or manual means for drying. Due to the retention of water in the tube wall, clinical blood collectors should quickly mix it upside down and make it fully contact with the blood in order to achieve the best anticoagulant effect.
As a professional manufacturer of blood vessel additives, Desheng has a complete range of product types, all of which are analytical grade. Additionally, the potassium salt of ethylenediaminetetraacetic acid has two properties of anhydrous and dihydrate as reagent raw materials, which can be chosen by customers themselves. At present, the domestic market has a high level of satisfaction with the use of blood collection additives produced by the company, which has been recognized by multiple customers.
