edta dipotassium salt,
[product name] tri potassium EDTA dihydrate
[Formula] edtak3 · 2H2O
[package specification] plastic bottle, 500g / bottle
[product 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, 25 ℃). Stable at room temperature. The main content of EDTA in the company is ≥ 99.0%. See the product test report for other indicators.
[main use] this product is specially used for anticoagulation of blood in vitro. It 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 cell composition of blood, not affect the white blood cell count and size, has the least impact on the morphology of red blood cells, and can inhibit the aggregation of platelets, which is suitable for general hematology test. In addition to the separation and test of platelets, it is not suitable for coagulation test and platelet kinetic energy test, nor for the determination of calcium ion, potassium ion, sodium ion, iron ion, alkaline phosphatase, creatine kinase and leucine aminopeptidase and PCR test.
The International Committee for standardization of Hematology (ICSH) recommended EDTA as the anticoagulant for blood cell count and classification. Compared with EDTA, it has higher solubility and faster anticoagulation speed.
[warning and prevention]
When impurities, foreign matters, abnormal smell, color, serious moisture absorption and expiration date occur in EDTA, it is forbidden to use.
Do not continue to use EDTA Tripotassium solution in case of turbidity.
This product is a chemical reagent with strong corrosiveness. It is forbidden to touch it directly. When splashing on the skin, wash with plenty of water. Splashing into eyes can be washed with plenty of water immediately. In case of emergency, it should be sent to hospital for examination and treatment immediately.
[storage conditions] the product can be sealed and stored in a cool and dry place, away from light and moisture. The aqueous solution of this product can be sealed and stored in sterile state at room temperature. It is recommended that the aqueous solution of this product be prepared and used immediately, and not stored in solution state for a long time.
