Refractive Index Performance Verification (PQ) kit

Refractive Index Performance Verification (PQ) Kit is a set of certified reference liquids used to verify, calibrate, and qualify refractometers in pharmaceutical and analytical laboratories.

🏭⚗️ Production
Reference liquids are prepared from high-purity compounds to provide precise and reproducible refractive indices. They are packaged in sealed containers to maintain stability, prevent contamination, and ensure consistent measurement performance.

🔬 Properties
Liquids are stable under recommended storage conditions and provide well-defined, reproducible refractive indices. These properties allow accurate verification of instrument performance, linearity, and precision during measurements.

🧪 Applications
In pharmaceutical and analytical laboratories, PQ kit is used for calibration, verification, and performance qualification of refractometers. It supports instrument qualification (IQ, OQ, PQ), routine performance checks, and method validation to ensure accurate, traceable, and regulatory-compliant refractive index measurements.

⚠️ Safety
Reference liquids should be handled according to standard laboratory safety protocols, including gloves and protective eyewear. They should be stored in a cool, dark place, and containers disposed of according to laboratory safety regulations.
