Versa 20×2/EVO

Versatile dual temperature control for the Evolution 300 and 600 Spectrophotometers
Product Overview

The Versa 20×2/EVO combines two Versa 20 cuvette holders for the Perkin Elmer LAMBDA 750 UV/Vis/NIR Spectrophotometer. It provides independent Peltier temperature control for both the sample and reference cuvettes. Use the Versa 20/EVO 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/EVO 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 two Versa 20×2/EVO cuvette holders replace the sample and reference cuvette holders and have the utilities conveniently routed under the front panel of the spectrophotometer. Operate the TC 1/Single Temperature Controller using the menu button or control via program T-App.
