Refractometer Abbe AR4 / AR4D - Used Laboratory Equipment and New Lab Instrument Supplies, UK

Refractometer Abbe AR4 / AR4D - Kruss

Only a small quantity of sample is needed to measure with the AR4D refractometer. It is perfect for solid, viscous and liquid samples (transparent or opaque). Measures refractive index (nD), dispersion (nF-nC) and concentration in Brix by the Abbe principle. Temperature controlled prism. With digital thermometer.
