Conductivity Solution 1.3 μS/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 conductivity meters, TDS meters, and other instruments measuring low 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 1.3 μS/cm conductivity value is achieved using high-purity deionized water with carefully controlled ionic content. The solution is supplied in chemically resistant, sealed, and light-protected containers to prevent contamination, CO₂ absorption, 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 low conductivity of 1.3 μS/cm. Exhibits excellent stability under recommended storage conditions. Minor variations in conductivity may occur after prolonged storage or exposure to air and temperature fluctuations; gentle mixing restores homogeneity without affecting the reference value.
🧪 Applications
Used in pharmaceutical, analytical, and educational laboratories for calibration, validation, and performance testing of conductivity meters and other low-conductivity measurement instruments. Suitable for method validation, routine QC analysis, equipment qualification (IQ/OQ/PQ), and compliance with pharmacopeial standards requiring ultra-low conductivity references. Ideal for ensuring accurate measurements in high-purity water analysis, formulation development, process control, 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.
