Product Description

Spectrophotometer (DOUBLE BEAM) is a solid state microprocessor based instrument designed for quick and accurate spectrophotometric analysis of any concentration. The use of diffraction grating in the monochromator produces a linear spectrum.

The double-beam spectrophotometer is a device that uses two rather than one beam of light to measure how light is absorbed during spectrophotometry. Unlike single beam units, the device allows for simultaneous measurement of a sample beam and a reference beam.

Double beam spectrophotometers operate faster and provide more reproducible results because they perform an automatic correction for the loss of light intensity as the beam passes through the sample and reference solution.
