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. RS-232C 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.
