 Double Beam UV-VIS Spectrophotometer is a compact and easy to operate instrument for spectrophotometric analysis of any concentration.
The output is available on a 24 x 2 line alphanumeric backlit LCD display in terms of %Transmission (%T), Absorbance (Abs.), and Concentration (Conc.).
The instrument has 1000 sample storage memory, printer output for printing data with any dot matrix printer. interface for computer can be provided on request.
The use of microcontroller had made it an extremely versatile and state-of-the-art instrument.
Facility for using 10 mm pathlength cuvette is provided.

The instrument operates at wavelength between 190 to 1100 nm.
The use of diffraction grating in the monochromator produces a linear spectrum.
The use of grating having very high resolution of 1200 lines/mm ensures a narrow bandwidth.
Deuterium lamp (D2) is used in the range 190 to 380 nm and Tungsten Halogen lamp (W) is used in the range 380 to 1100 nm.
