Jasco V-650 UV-Vis Spectrophotometer

The V-650 is a double-beam spectrophotometer with a photomultiplier tube detector. The high sensitivity of the photomultiplier tube detector enables accurate measurements of low concentration samples. The light source consists of a Deuterium lamp (190 nm. to 350 nm) and a Halogen lamp (330 nm to 900 nm). The advanced optical design results in high optical throughput and allows the bandwidth to be set as low as 0.1 nm for high resolution work such as gas and vapor phase spectroscopy. Low stray light slit settings provide excellent linearity of up to 4 absorbance units.
