Conductivity solution 15.0 μS/cm

Conductivity Solution 15.0 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, exceptional purity, and minimal contamination. The 15.0 μS/cm value is achieved using trace-level concentrations of high-purity potassium chloride dissolved in ultrapure, ultra-low-conductivity water, with rigorous control of temperature, CO₂ uptake, and ionic background. The solution is packaged in chemically resistant, hermetically sealed, and light-protected containers to prevent evaporation, airborne contamination, or conductivity drift. Each batch is validated according to USP <645>, EP 2.2.38, and recognized electrochemical calibration standards to ensure accuracy, uniformity, and reproducibility.

🔬 Properties
A clear, colorless aqueous solution with a defined conductivity of 15.0 μS/cm at 25 °C. Exhibits excellent stability under recommended storage conditions. Due to its extremely low ionic strength, minor changes in conductivity may occur with trace contamination or temperature variation; gentle mixing restores homogeneity without altering the designated value. Temperature-compensated values adhere to internationally accepted conductivity standards.

🧪 Applications
Used in pharmaceutical, analytical, environmental, and industrial laboratories for calibration, validation, and performance testing of high-precision, low-range conductivity meters and sensors. Suitable for ultrapure water systems, purified water quality verification, method validation, routine QC analysis, and equipment qualification (IQ/OQ/PQ). Ideal for research applications requiring highly sensitive conductivity references, trace ionic monitoring, and evaluation of high-resistivity water purification systems.

⚠️ Safety
Considered low-hazard but should be handled using 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 to prevent changes in purity or conductivity. Dispose of according to pharmaceutical laboratory waste regulations and environmental safety guidelines.
