Uses

• Medical Field
  • Blood Anticoagulation: It is a commonly used anticoagulant in clinical blood tests and is used in blood collection tubes. It can chelate calcium ions in the blood, inhibit blood coagulation, ensure the smooth progress of blood collection, and ensure the accuracy and reliability of blood samples. It is suitable for general hematological tests.
• Industrial Field
  • Metal Ion Chelating Agent: It can form stable complexes with various metal ions. In the electroplating industry, it is used as an additive, which can increase the deposition rate and uniformity of metal on the cathode and improve the electroplating quality.
  • Water Treatment: It is used to treat heavy metal ions such as lead, mercury, and cadmium in industrial wastewater, separating them from the wastewater to achieve the purpose of purifying water quality.
• Food Field
  • As a food additive, it is used to chelate metal ions such as iron, copper, and lead, preventing metal ions in food from reacting with other components, affecting the taste and quality of food.
• Cosmetic Field
  • Chelating Metal Ions: It can effectively chelate metal ions, prevent the oxidation of metal ions to cosmetics, and ensure the quality and stability of products.

Packaging and Storage

• Packaging: Usually packaged in plastic or glass bottles. Common packaging specifications include 500g/bottle, 1kg/bottle, etc.
• Storage: It should be stored in a dry, cool, and well - ventilated place, away from direct sunlight, fire sources, and heat sources. Keep the container sealed to prevent moisture and contamination.
