Refractive Index Standards

A range of sucrose standards for use in the calibration and verification of all types of refractometer e.g. handheld, Abbe and high accuracy digital instruments. Sucrose standards are manufactured using traceable high purity materials to four decimal places following ICUMSA methods. They are the only standards available world -wide which carry a full BS EN ISO / IEC17025 certificate of calibration with each bottle.

Sucrose solutions are ideal for use in the food and beverage industries and are available in various concentrations depending on the end users application. Unique concentrations can also be manufactured upon request.

You can save money by using our yearly subscription package, which also allows you to place one order while still receiving a regular supply of the chosen certified standard.

Oil RI Standards

Calibration Oils are one of the most commonly used materials for calibrating refractometers as they have good traceability, particularly to NIST. Having a high temperature co-efficient, calibration oils are used where strict temperature control is adopted, either by Peltier or external waterbath between 10 and 75 °C. Calibration Oils are batch manufactured and so values may differ slightly from published data. Oils are supplied in multipacks of 5 x 5ml bottles with a certificate of calibration, MSDS and pipettes and have an expiry date 12-months from date of dispatch.

For refractometers operating at high temperatures where water starts to evaporate, an oil may be used as a zero calibration medium. Typical applications include those in the confectionery, edible oil and mineral oil marketplaces.
