Tri-potassium EDTA / EDTA K3

[Product Name]Tri-potassium EDTA

[Formula] EDTAK3·2H2O

[Package Specification] Plastic bottle, 500g/bottle

[Performance] White crystal powder, odorless, soluble in water, easy to absorb moisture, molecular weight of 442.56, pH value of 7.3±1 (5% aqueous solution, g/ml,), solubility in water≥60% (g/ml, at 25℃). Stable at room temperature. The main content of tri-potassium EDTA≥99.0%. See the product test report for other indicators.

[Application] This product is specially used for in vitro anticoagulation of blood, and is an anticoagulant additive for clinical blood test. It is used for blood sample pretreatment (anticoagulation treatment) in the process of clinical blood collection and test.

[Scope of application] EDTA salt can protect the cellular components of the blood, does not affect the white blood cell count and size, has the least effect on the red blood cell morphology, and can inhibit the aggregation of platelets, suitable for general hematological tests. Except for the isolation and examination of platelets, it is not suitable for coagulation test and platelet kinetic energy test, nor for the determination of calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase and leucine amino peptidase and PCR test.

The international committee for standardization of hematology (icsh) recommends the preferred anticoagulant for blood counts and classification of tripotassium EDTA. Compared with dipotassium EDTA, it has higher solubility and faster anticoagulation rate.
[Method of use] the product is dissolved with deionized water (distilled water), prepared into a solution with a certain concentration and content, and then added into the blood collection tube.
