The Model DBUV-VIS-6400VB is a user-friendly Double Beam UV-VIS Spectrophotometer. Inbuilt color touch screen which displays all Menu and spectrum data. Highly Efficient monochromator with a holographic grating keeps straylight to a minimum and offers excellent optical resolution. The use of a Silicone Photodiode tube as a detector offers exceptional sensitivity. The Double Beam Optical System coupled with an efficient and well proven electronic control system ensures high stability and low background noise.
