Certified Reference Materials serve as the gold standard for verifying instrument accuracy. Regular calibration ensures your equipment delivers consistent, reliable data—whether for production control, research, or regulatory compliance. Each CRM is certified under ISO/IEC 17025:2017 and accredited by UKAS (United Kingdom Accreditation Service), meeting the highest global benchmarks through ILAC recognition.
Full Range of Calibration Solutions Available
Low Brix Water-Based Standards
Ideal for calibrating instruments that operate within the low °Brix or refractive index range, commonly used in beverage and juice quality testing.
High RI Oil-Based Calibration Liquids
Optimized for applications requiring broader refractive index coverage, such as edible oil analysis or petrochemical testing. Temperature control is strongly recommended to ensure precision.
Sucrose-Based Standards for Refractometers with ATC
Supplied in user-friendly dropper bottles, these sucrose calibration solutions are ideal for equipment with automatic temperature compensation. Designed to minimize contamination and support accurate °Brix readings.
Quartz Control Plates for Polarimeter Validation
Engineered for angle and sugar scale verification in polarimetry, with optional UKAS and PTB-traceable certification. Suitable for ±30°, ±10°, ±5°, 15°, 34°, and 50° rotations. Sets available upon request.
AG Calibration Liquids (Water-Based)
Precision calibration for instruments measuring low °Brix or refractive index values. These solutions offer long shelf life (minimum 12 months) and come in practical multipacks.
