Refractometers

What are refractometers and what to ask when buying these instruments for your laboratory

Density meters and refractometers continue to evolve to suit researchers’ ever-expanding needs

Many factors can negatively affect accuracy in refractometry; the secret is to eliminate them

A material’s refractive index—essentially how much it bends lights—can be used to describe the material and its use.

Refractometer manufacturers quote accuracy and reproducibility to the fourth, fifth, and sometimes even the sixth decimal places. A good manufacturer will only advertise this level of accuracy after carefully running standards.
