The following article describes in detail the cleaning of the internal electrical contacts to resolve issues of the reading value continually scrolling.

Bilirubinometer Control Cuvettes Validation

The Calibration, High, and Low Level Check Cuvettes used with the UNISTAT BILIRUBINOMETER degrade over time. Reichert recommends you send these in annually for reclassification.

Refractometer Maintenance Guide

Based upon decades of customer feeback, Reichert is pleased to offer the following guidelines to help maintain your refractometer in optimal operating condition.

Serial Port Communications

The bench-top refractometers offered by Reichert are capable of downloading data to, and receiving commands from a computer via the serial port.

Calibration - What is it?

What is calibration and why is it important to verify the calibration of a refractometer?

Converting Refractometer Readings to Actual Concentration

Refractometers may be used to test many types of liquid samples. Though they are designed with a scale that is particular to one specific product, they are versatile enough for use in any application where a concentration reading is desired.

Calibration Testing/Verification

Verifying the reading accuracy of a refractometer is as simple as following these instructions.

Measuring Plastics with an Abbe Refractometer

Following is a method used for measuring transparent solid materials such as plastics on a traditional Abbe type refractometer.

Official Methods List for Refractometers

Attached is a reference list of just some of the official methods which have been developed for refractometers.

Temperature Coefficient Calculation and Temperature Correction

Temperature is a critical component of a refractometer measurement. As temperature increases, refractive index decreases. To correct for this so that readings can be accurately compared, the temperature coefficient of the sample must be determined.
