What are the differences among dipotassium EDTA, tripotassium EDTA and disodium EDTAE? I believe many people don't know, so let's talk about the differences in the uses of these three products today!

Ethylenediaminetetraacetic acid dipotassium (EDTA-2K) ethylenediaminetetraacetic acid (abbreviated as Dipotassium EDTA) is an amino polyacid.It is a general-purpose strong complexing agent for forming complexes with most metal ions.Dipotassium EDTA is an anticoagulant commonly used in blood analyzers. It has the characteristics of good anticoagulation effect and less influence on the morphology of blood cells. Blood analysis is a routine test item in clinical medicine. The vast majority of patients undergo this test. From the beginning of manual detection to fully automatic detection.

Tripotassium EDTA is an amino polyacid.Although the integration of EDTA has long been used for extraction, cation exchange, separation of rare elements, volumetric analysis of calcium, magnesium, and barium, softening of hard water, and use as masking agent, metal cleaning agent, antidote for heavy metal poisoning, bactericide, etc. However, in-depth research on its structure and integration mechanism was done after 1958.

Some studies have shown that unexplained low platelet counts are found in blood analysis with EDTA-K3 anticoagulation, and the patient should be manually checked for blood slices and PLT manual counts, or diluted with unanticoagulated peripheral blood. Check the PLT count directly with the instrument for blood cell analysis to correctly understand the true level of the patient's PLT. Especially cancer patients, autoimmune diseases, pulmonary heart disease, pregnant women, advanced liver disease and other patients.

Disodium EDTA is often used in coordination burettes to measure the composition of metal ions. Disodium EDTA has main uses in industrial production such as dyes, food, and pharmaceuticals. Disodium EDTA is milky white crystalline particles or powder, odorless and odorless. It can dissolved in water, not easily in alcohol. It is a key antioxidant that chelates metal ions in aqueous solutions. And can avoid discoloration, mildew, turbidity and air oxidation damage of vitamin C caused by metal materials, and also improve the antioxidant of vegetable oils,a small amount of metal materials such as iron and copper in vegetable oils can promote the air oxidation of vegetable oils.

According to the application quality standards of food preservatives in my country, disodium EDTA can be used in canned aquatic products, canned fruits with red bean syrup and chestnut, etc. The maximum demand is 0.25mg/kg. It can maintain the color, aroma and taste of canned fruit food. For canned aquatic products such as crab and shrimp, the addition of disodium EDTA can avoid the dissolution of Struvite, a laminated glass-like crystal, to ensure the quality of processed products. . It is also used as stabilizer and adhesive for sauce products and canned fruits, and the maximum demand is 0.25g/kg.

I believe the above make it clear for the use of dipotassium EDTA, tripotassium and disodium EDTA. But all ours are produced for blood collection tube additives , pls feel free to contact if you need them.
