Features and Benefits

  • We provide KCl with an exceptional trace metal purity of 99.999%, ensuring optimal pH stability and minimizing the risk of unwanted reactions.
  • Low levels of trace metals (<15ppm) are crucial to avoid interference in sensitive biochemical assays.
  • High purity minimizes corrosion and ensures efficient heat transfer, while low impurity levels (<15ppm) prevent unwanted reactions, and overall purity guarantees thermal stability under reactor conditions.

General description

Potassium chloride (KCl) is a water-soluble metal salt that comprises of potassium and chlorine. It can be extracted from minerals and salt water. KCl can be used in industries such as cosmetics, food, biomedical, chemical and fertilizer.
