Conductivity Solution 111.0 mS/cm is a pharmacopeial-grade reference solution designed for use in pharmaceutical quality control, laboratory calibration, and analytical testing for the calibration and performance verification of high-range conductivity meters, TDS meters, and other instruments measuring high ionic conductivity in aqueous systems.
🏭⚗️ Production
Prepared under strictly controlled GMP- and pharmacopeial-compliant conditions to ensure precise conductivity, chemical stability, and minimal contamination. The 111.0 mS/cm conductivity value is achieved using high-purity salts dissolved in deionized water at accurately controlled concentrations. The solution is supplied in chemically resistant, sealed, and light-protected containers to prevent contamination, evaporation, or degradation. Each batch is validated according to USP <645>, EP 2.2.38, and relevant pharmaceutical testing standards to ensure accuracy, uniformity, and reproducibility.
🔬 Properties
A clear, colorless aqueous solution with a defined high conductivity of 111.0 mS/cm. Exhibits excellent stability under recommended storage conditions. Minor variations in conductivity may occur after prolonged storage or exposure to extreme temperatures; gentle mixing restores homogeneity without affecting the reference value.
🧪 Applications
Used in pharmaceutical, analytical, and educational laboratories for calibration, validation, and performance testing of high-range conductivity meters and related instruments. Suitable for method validation, routine QC analysis, equipment qualification (IQ/OQ/PQ), and compliance with pharmacopeial standards requiring high-conductivity references. Ideal for ensuring accurate measurements in formulation development, process control, water quality testing, and laboratory research.
⚠️ Safety
Considered low-hazard but should be handled according to standard laboratory safety practices. Avoid ingestion, inhalation, and direct contact with skin and eyes. Use appropriate personal protective equipment, including gloves, goggles, and a lab coat. Store in tightly sealed, light-protected containers in a cool, dry environment. Dispose of according to pharmaceutical laboratory waste regulations and environmental safety guidelines.
