qX2/std

Air-cooled, Peltier-controlled cuvette holder on a standard base and support post
Product Overview

The qX2/std is a temperature-controlled cuvette holder with two optical ports for use with absorption spectroscopy. This model is not adapted to a specific spectrophotometer. The cuvette holder is mounted on a post and simple base. It is intended for home-built instruments or for simply attaching to an optical breadboard. Use the qX2/std to set and maintain precise sample temperatures and stir at a steady reproducible rate, while bathing the cuvette in a controlled gaseous environment. Although dependent on rapid, precise Peltier technology, no circulating water is required for normal operation from 0 °C to 110 °C. Purchase the low temperature option, consisting of a windowed vest and capability for liquid cooling, and operate the qX2/std from 0 °C down to -40 °C. Purchase the extended temperature option to extend operation a little below -40 °C or above 110 °C to 150 °C. Control the qX2/std, using the TC 1B Temperature Controller included in the purchase price. For additional control and temperature monitoring, use Quantum Northwest’s computer control software, T-App, available for purchase.
