Versa 20×2/Dynamica

Versatile dual temperature control for Dynamica Spectrophotometers
Product Overview

The Versa 20×2/Dynamica combines two Versa 20 cuvette holders for use in Hitachi UV-Vis spectrophotometers. It provides independent Peltier temperature control for both the sample and reference cuvettes. Use the Versa 20/Dynamica 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/Dynamica 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/Dynamica 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 control via program T-App.
