Versa 20/Hitachi

Versatile Peltier-driven temperature control for Hitachi Spectrophotometers
Product Overview

The Versa 20/Hitachi is a versatile design, providing temperature control to a single cuvette in the forward sample beam of the spectrophotometer. The Versa 20/Hitachi is ideal for work in the biological range of 0 °C to 110 °C, either to observe absorbance spectra at precisely maintained temperatures, or for temperature ramping, to observe how absorbance changes with temperature. To work at cold temperatures, purchase a Windowed Jacket, purge with dry gas and work down to -40 °C. For even more demanding work, purchase the extended temperature option and run the Versa 20/Hitachi up to 150 °C or down to below -40 °C. The Versa 20/Hitachi replaces the sample tray (base and front panel) of the spectrophotometer, with utilities brought conveniently to the front panel. This unit may be controlled using the menu button on the front of the TC 1/Single controller or through program T-App available from Quantum Northwest.
