REFRACTOMETERS AT GEM SCIENTIFIC

Used to measure the concentrations of aqueous solutions, a digital refractometer only requires a few drops of a liquid in order to provide fast and accurate results, allowing you to use your samples as efficiently as possible. Our range features handheld refractometers and benchtop refractometers with models that are designed for measuring salt, fructose, glucose, inverted sugar content and general-purpose sugars.

HOW DIGITAL REFRACTOMETERS WORK

Digital refractometers use an LED light that passes through a prism in contact with the sample you have chosen. An image sensor then measures the degree to which the light changes direction in order to determine the concentration of the solution that it is testing for. Digital refractors are extremely effective, accurate, long-lasting and easy to use, and are available from brands including Bellingham and Stanley. To find out more about the refractometry products that we offer, including sugar refractometers and optical refractometers, browse our selection of brands today.
