[Product Name] Dipotassium EDTA
[Package Specification] Plastic bottle, 500g/bottle
[Performance] White crystal powder, odorless, soluble in water, easy to absorb moisture, molecular weight of 404.6, pH value of 4.8�±1 (5% aqueous solution, g/ml), solubility in water â?¥ 60% (g/ml, 25â??). Stable at room temperature. The main content of EDTA in our company is â?¥ 99.0%. See the product test report for other indicators.� � 
[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 morphology of the red blood cell , and can inhibit the aggregation of platelets, which is suitable for general hematological test. 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.
International Committee for hematology Standardization (ICSH) recommended dipotassium EDTA as anticoagulant for blood cell count and classification. Compared with tripotassium EDTA, it has lower solubility and slower anticoagulation speed.

[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.
