Potassium Chloride Solution 3M is a pharmacopeial-grade reference and working solution designed for use in pharmaceutical quality control, electrochemical measurements, and laboratory analytical procedures, particularly as an electrolyte filling solution for ion-selective electrodes, pH electrodes, and electrochemical sensors requiring stable high-ionic-strength environments.
🏭⚗️ Production
Prepared under strictly controlled GMP- and pharmacopeial-compliant conditions to ensure precise molarity, chemical purity, and minimal contamination. The 3M concentration is achieved using high-purity potassium chloride dissolved in deionized water under controlled ionic and conductivity parameters. The solution is filtered, degassed, and packaged in chemically resistant, sealed, and light-protected containers to prevent evaporation, crystallization, or contamination. Each batch is validated according to USP <791>, EP 2.2.35, and relevant electrochemical testing standards to ensure accuracy, uniformity, and reproducibility.
🔬 Properties
A clear, colorless aqueous solution with a defined concentration of 3 moles of potassium chloride per liter. Exhibits high ionic strength, excellent conductivity, and remarkable chemical stability under recommended storage conditions. Occasional salt crystallization may occur at low temperatures; gentle warming and mixing fully restore homogeneity without affecting concentration.
🧪 Applications
Used in pharmaceutical, analytical, and educational laboratories as a standard electrolyte, electrode filling solution, and calibration medium. Suitable for pH electrode reference chambers, chloride electrodes, electrochemical sensor stabilization, conductivity system calibration, method validation, routine QC analysis, and equipment qualification (IQ/OQ/PQ). Also applied in formulation development, water analysis, and electrochemical research requiring stable chloride ionic activity.
⚠️ Safety
Considered low-hazard but should be handled according to standard laboratory safety practices. Avoid ingestion, inhalation of aerosols, and direct contact with skin and eyes. Use appropriate personal protective equipment, including gloves, goggles, and a lab coat. Store in tightly sealed, contamination-free containers in a cool, dry environment. Dispose of according to pharmaceutical laboratory waste regulations and environmental protection guidelines.
