Simple Introduction Of EDTA K2,EDTA K3 and EDTA Na2

What are the differences among EDTA K2,EDTA K3 and EDTA Na2? 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 K2) ethylenediaminetetraacetic acid is an amino polyacid.It is a general-purpose strong complexing agent for forming complexes with most metal ions.EDTA K2 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.

EDTA K3 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.

EDTA Na2 is often used in coordination burettes to measure the composition of metal ions. EDTA Na2 has main uses in industrial production such as dyes, food, and pharmaceuticals. EDTA Na2 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, EDTA Na2 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 EDTA Na2 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 EDTA K2,EDTA K3 and EDTA Na2. But all ours are produced for blood collection tube additives, pls feel free to contact if you need them.
