کانداکتیویتی(هدایت سنجی) 146.9 μS/cm

Conductivity Solution 146.9 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 low-to-mid-range conductivity meters, cells, and electrochemical measurement systems.

🏭⚗️ Production
Prepared under strictly controlled GMP- and pharmacopeial-compliant conditions to ensure precise conductivity, stable ionic strength, and minimal contamination. The 146.9 μS/cm value is obtained using high-purity potassium chloride dissolved in ultrapure, low-conductivity deionized water, with stringent control of temperature, CO₂ exposure, and ionic composition. The solution is packaged in chemically resistant, sealed, and light-protected containers to prevent evaporation, 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 146.9 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 international conductivity standards.

🧪 Applications
Used in pharmaceutical, analytical, environmental, and industrial laboratories for calibration, validation, and performance testing of conductivity meters, probes, and electrochemical sensors operating in the low-conductivity range. Suitable for method validation, routine QC analysis, equipment qualification (IQ/OQ/PQ), and compliance with pharmacopeial conductivity requirements. Ideal for use in purified water systems, ultrapure water monitoring, formulation control, and research applications requiring accurate, low-range conductivity references.

⚠️ 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.
