T8DCS Double Beam UV-Vis Spectrophotometer


T8DCS is a high performance double beam spectrophotometer with a continuously selectable spectral bandwidth from 0.1-5nm.

It meets various demands for spectral bandwidth from users in different industries especially pharmaceutical industry and scientic research field.

The Czerny-Turner Monochromator with a holographic grating keeps stray light to a minimum and offers excellent optical resolution.


The use of a photomultiplier tube as detector delivers exceptional sensitivity.


The T8DCS’ true double-beam optical system coupled with an efficient and well proven electronic control system ensures high stability and low background noise.
