Laboratory refractometers — professional optical instruments

Refractometry is one of the most common analytical measurement methods. The technique allows you to identify chemical compounds, conduct quantitative, structural analysis, determine the physical and chemical parameters of substances. Laboratory refractometers buy it is important to measure the concentration of solutions using the phenomenon of light refraction in addition to the research arsenal.

Working principle of the refractometer

Laboratory refractometers, regardless of price, measure data based on the refractive indices of light in different media. If the density of a substance increases, the refractive index is directly proportional to it. The device consists of the main elements:

A glass prism with a high refractive index is the main part.
Special glass, which covers the glass prism, presses down and evenly distributes the examined liquid.
Lens system.
Calibration screw for adjustment.
A bimetal plate for correcting deviations caused by temperature.

To make measurements, a liquid is applied to the prism. The refractometer emits light that passes through the main elements. When it hits the scale, depending on the refraction, the beam ends up at a certain graduation position. One zone is illuminated, the other is in shadow. The reading is read along the boundary between these areas.

Types of laboratory refractometers

Modern models of devices have a different configuration, which provides convenience of use and the formation of prices for laboratory refractometers. Equipment is divided into three groups:

Portable — mobile and compact, used in any conditions.
Laboratory — used to analyze substances in the laboratory.
Industrial — control technological processes at production facilities.

The most popular are portable refractometers. The devices are handheld and digital. Handheld devices have portability, provide accurate results. Digital models are equipped with an LCD screen that displays measurement data. Most refractometers have additional functions: measurement of density, refractive index, conversion of the result, support of the temperature mode of the examined liquid.

It is important to note that before using the device, it must be calibrated (adjusted). This will maximize the accuracy and reliability of the results. For this purpose, distilled water is used. It does not affect the phenomenon of light refraction, so it shows a zero indicator on the lens.
