qX2/8454

Air-cooled, Peltier-controlled cuvette holder for the 8452, 8453 and 8454 Diode Array Systems
Product Overview

The qX2/8454 is a temperature-controlled cuvette holder with two optical ports for use in the open sample compartment of your 8452, 8453 and 8454 Diode Array System. 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 qX2/8454 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. Operate the qX2/8454 using the Agilent ChemStation software (with a Quantum Northwest driver available now as a free download), or use 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.
