Product Description
Confidence in every Brix or refractive index result starts with a quick check against a known reference. These calibration standards let you verify your refractometer before a run, catching drift early so production, QC and field readings stay accurate and defensible. Regular checks are a simple step toward reliable records.
This listing is for catalog number 45000-OS200: Refractometer Standard, Water-based, 0.00% Brix 1.33297 nD (20°C), 7.4 mL/0.25 oz. Two standards are offered, each in a 7.4 mL (0.25 oz) bottle. The water-based standard reads 0.00% Brix at 1.33297 nD and serves as a zero point, while the oil-based standard reads 60.0% Brix at 1.4420 nD for checking the upper part of the scale. Both values are referenced at 20°C. Place a few drops on the prism and compare the reading. Add it to your LIGHT LABS order and keep your lab stocked.
Key Features
