Which one is commonly used as edta disodium or edta potassium anticoagulant?
Both edta disodium and edta dipotassium contain the substance edta. From the surface morphology, they are similar, but they also have fundamental differences. In addition to the differences between sodium salt and potassium salt, although both can be added to the test tube as anticoagulants, they are also widely used and commonly used. Now let's introduce to you in detail which one is commonly used as anticoagulant, edta disodium and edta potassium?
Properties of edta disodium and edta potassium
If you want to know which kind of common anticoagulant is edta disodium or edta potassium, you need to clearly understand its performance. Both of them are white crystalline powder with no odor and can dissolve in water, but the difference is the PH value and the metal ions contained. The PH value of edta disodium is 5.5, and the PH value of edta potassium is 4.8. One contains sodium ions and the other contains potassium ions. Edta dipotassium is usually in a spray dry state on the inner wall of the test tube, which does not interfere with cell components. In addition, because its solubility is higher than edta dipotassium, edta dipotassium is more popular in the market and is a commonly used anticoagulant.
Use of edta disodium and edta potassium
Edta disodium and edta dipotassium can be complexed with most metal substances due to their own properties, so in blood analysis, both can directly play an anticoagulant effect in test tubes, and are widely used in the medical field. However, it should be noted that edta dipotassium is used more frequently than edta disodium. edta disodium is mainly used in food or industrial fields, because it can be used as a key antioxidant to avoid deterioration, discoloration or other effects caused by air oxidation caused by various metal materials or substances.
From the above two aspects, although edta disodium and edta dipotassium have similar performance and can be used as anticoagulants by complexing metal ions, edta dipotassium will be more popular and commonly used as anticoagulants due to market demand and solubility. However, edta disodium may be used more in industry, but the choice of which anticoagulant to use is based on your own needs. As long as the detection effect can be achieved, any one can be used.
Desheng Biochemical is a manufacturer that has the advantage of supplying EDTA series products, and the company started as an additive for blood collection vessels from the very beginning of its establishment, followed the market changes, and later developed other types of products, such as biological buffers, luminous reagents and chromogenic substrates, enzyme preparations, etc. Although there are many products, the additives for blood collection tubes are always the core products. For this reason, the company has also set up a special testing department to accurately control the quality of products, and the stock is sufficient.
