VariRef – Refractometer

VariRef Modular Refractometer

Overview
VariRef is a high-precision, modular benchtop refractometer for liquids and solids. It combines rapid Peltier temperature control with a flat, easy-to-clean sample room, delivering fast, reliable refractive index and Brix measurements for QC and R&D.

Key features
• Modular platform with interchangeable sample room doors for single measurements or flow-through.
• Fast temperature stabilisation and ambient temperature compensation for stable results.
• LED light source at 589 nm and durable sapphire prism.
• Multi-point calibration across the full measuring range.
• Intuitive 7 inch touchscreen, LIMS and ELN ready, minimal maintenance.

Performance
• Measuring range typically 1.29000 to 1.58000 RI and 0 to 100 Brix, with high resolution options.
• Repeatability options down to ±0.000005 RI or ±0.006 percent Brix depending on model.
• Small sample volume from about 0.6 ml for routine QC.

Temperature control
• Peltier control typically 5 to 80 or 5 to 100 °C depending on configuration, precision about ±0.03 °C, resolution 0.01 °C.

Compliance and data integrity
• 21 CFR Part 11 capable with audit trails and user management.
• Conforms with common methods and pharmacopoeias for pharmaceutical and food QC.

Typical applications
• Concentration checks and purity control in pharma and fine chemicals.
• Brix and formulation control in food and beverages.
• Incoming goods testing and routine release in regulated environments.

What makes it different
VariRef’s modular design, fast temperature control and self-checking functions help teams achieve repeatable, traceable results with minimal cleaning and downtime, making it a robust choice for GMP aligned laboratories.
