• Application Fields
  • Blood Anticoagulation: EDTA dipotassium salt can combine with calcium ions in blood to form a stable complex, thus preventing blood coagulation. It is a commonly used blood anticoagulant, suitable for general hematological examinations, such as blood routine examinations. The International Council for Standardization in Haematology (ICSH) recommends EDTA dipotassium salt as the preferred anticoagulant for blood cell counting and classification.
  • Metal Complexing Agent: As a complexing agent, it can be used to complex calcium, magnesium and other metal ions, and is widely used in chemical, pharmaceutical and other fields. For example, in cosmetics, it can complex metal ions to improve the stability of products; in water treatment, it can remove metal ions in water.
• Storage Conditions
  • It should be stored in a sealed container, in a cool and dry place, and avoid long - term exposure to air.
