Human K2 EDTA plasma samples from donors; tested and found negative for HIV, HBV, HCV and Syphilis.
K2 EDTA. The inner wall of EDTA tubes is coated with spray-dried K2 EDTA or K3EDTA. EDTA acts as an anticoagulant, binding the calcium ions and interrupting the clotting cascade. These tubes are used primarily in hematology.
K2EDTA tubes contain di-potassium K2EDTA which blocks the coagulation cascade. Selected tubes are also available with transparent labels.
EDTA K2 POWDER
The K2 EDTA Blood Collection Tube is a lavender top tube which is used primarily in hematology. The inner wall is coated with spray-dried K2 EDTA which acts as an anticoagulant, binding calcium ions and interrupting the clotting cascade. K2 EDTA Blood Collection Tubes with Gel Separator and K3 EDTA Blood Collection Tubes are also available. Pink caps for immunohematology are available as well.

Ethylenediaminetetraacetic acid, also known as EDTA, belongs to an organic compound. Its appearance is white crystalline powder, odorless and tasteless, with a melting point of 250°C. It is soluble in alkaline solutions such as sodium hydroxide, sodium carbonate and ammonia solution, slightly soluble in water, and insoluble in organic solutions such as ethanol. Ethylenediaminetetraacetic acid is mainly used as disodium salt, and its application fields are many and wide-ranging. Because ethylenediaminetetraacetic acid is a chelating agent that can combine with divalent metal ions such as Mg2+, Ca2+, Mn2+, and Fe2+. Most nucleases and some proteases require Mg2+ to function, so ethylenediaminetetraacetic acid is often used as an inhibitor of nucleases and proteases.
Product packaging
In addition, the preparation method of ethylenediaminetetraacetic acid is as follows:
Ethylenediamine reacts with formaldehyde and sodium cyanide. Mix 60% ethylenediamine aqueous solution, 30% sodium cyanide aqueous solution and sodium hydroxide, keep at 20℃ and mix for 0.5h. Then the aqueous formaldehyde solution was added dropwise. After the reaction, water was distilled off under reduced pressure. Then repeat the above operation, adding excess formaldehyde for the last time to completely react the sodium cyanide. Adjust the pH to 1.2 with dilute acid. A white precipitate separated out, filtered, washed with water, and dried at 110°C.
