Versa 20×2/Cary300

Versatile dual temperature control for the Cary 100 and 300 UV-Vis-NIR Spectrophotometers
Product Overview

The Versa 20×2/Cary300 combines two Versa 20 cuvette holders for use in the dual-beam Cary 100 and Cary 300 UV-Vis Spectrophotometers. It provides independent Peltier temperature control for both the sample and reference cuvettes. Use the Versa 20 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/Cary300 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/Cary300 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. Use an ADL program for temperature ramping with WinUV ADL Shell software.
