Conductivity 20.0 micro
Conductivity Solution 20.0 μS/cm is a pharmacopeial-grade reference solution designed for use in pharmaceutical quality control, ultrapure water monitoring, and analytical testing for the calibration and performance verification of very low-range conductivity meters, cells, and high-sensitivity electrochemical measurement systems.
🏭⚗️ Production
Prepared under strictly controlled GMP- and pharmacopeial-compliant conditions to ensure precise low-level conductivity, high purity, and minimal contamination. The 20.0 μS/cm value is achieved using trace concentrations of high-purity potassium chloride dissolved in ultrapure, ultra-low-conductivity water, with stringent control of temperature, ionic background, and CO₂ exposure. The solution is packaged in chemically resistant, hermetically sealed, and light-protected containers to prevent contamination, evaporation, or conductivity drift. Each batch is validated according to USP <645>, EP 2.2.38, and internationally recognized electrochemical calibration standards to ensure accuracy, uniformity, and reproducibility.
🔬 Properties
A clear, colorless aqueous solution with a defined conductivity of 20.0 μS/cm at 25 °C. Exhibits excellent stability under recommended storage conditions. Slight conductivity variations may occur due to temperature changes or prolonged exposure to air; gentle mixing restores homogeneity without altering the reference value. Temperature-compensated values are traceable to internationally accepted conductivity standards.
🧪 Applications
Used in pharmaceutical, analytical, environmental, and industrial laboratories for calibration, validation, and performance verification of low-range conductivity meters and sensors. Particularly suitable for ultrapure water systems, high-resistivity water testing, method validation, routine QC analysis, and equipment qualification (IQ/OQ/PQ). Ideal for research requiring accurate low-range conductivity references, trace ionic monitoring, and water purification process evaluation.
⚠️ 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, light-protected containers in a cool, dry environment. Dispose of according to pharmaceutical laboratory waste regulations and environmental safety guidelines.
