Versa 20×2/Shimadzu

Versatile dual temperature control for Shimadzu UV-Vis-NIR Spectrophotometers
Product Overview

The Versa 20×2/Shimadzu combines two Versa 20 cuvette holders for use in Shimadzu UV-Vis spectrophotometers. It provides independent Peltier temperature control for both the sample and reference cuvettes. Use the Versa 20/Shimadzu in the biological range of 0 °C to 105 °C, or non-aqueous samples, purchase the extended temperature option and run the Versa 20×2/Shimadzu up to 150 °C. Add a Windowed Jacket, purge with dry gas and run the temperature to well below zero. If necessary, run the sample and reference cuvettes at different temperatures. The Versa 20/Shimadzu replaces the cuvette holder base and the front panel of the spectrophotometer, with utilities brought conveniently to the front panel. Operate the TC 1/Single Temperature Controller using the menu button or through program T-App available from Quantum Northwest. When this unit is used in a Shimadzu UV-1800, a special version of T-App, called T-App(S) can be used to record absorbances from the spectrophotometer and plot them vs temperature.
