Versa 20/8453

Versatile Peltier-driven temperature-controlled cuvette holder for the Olis Upcycled HP 8453 Diode Array System
Product Overview

The Versa 20/8453 is a versatile holder providing temperature control for a single cuvette. It is easy to mount in the open sample compartment of the HP (or Agilent) 8453 Diode Array UV-Vis spectrophotometer.

The Versa 20/8453 is ideal for work in the biological range of 0 °C to 110 °C. To work at colder temperatures, purchase a Windowed Jacket, purge with dry gas, and work below 0 °C. For even more demanding work, purchase the extended temperature and run the Versa 20/8453 up to 150 °C or down to below -40 °C. Questions? Quantum Northwest offers a complimentary downloadable guide to working with your benchtop spectrometer at high and low sample cuvette temperatures.

It is easy to operate the Versa 20/8453 using the TC 1 Temperature Controller, included in the purchase price. The sample temperature, stirring speed, and temperature ramp rate may be controlled manually using the TC 1 menu control buttons on the front panel, or by using Quantum Northwest’s computer control software, T-App, available for purchase. If you use ChemStation to operate the HP 8453, you can simultaneously use T-App to control the Versa 20/8453.

No matter how you choose to control the Versa 20/8453, you will enjoy the power to capture absorbance spectra at precisely maintained sample temperatures, and to observe how sample absorbance changes with temperature. With the Versa 20/8453, a wide range of Peltier-based temperature control is now available for your existing Diode Array UV-Vis spectrophotometer. Easily plan and execute experiments that were not previously possible.

Many experiments will benefit from the Versa 20/8453 alone. If you have greater needs, our partnership with OLIS, Inc. of Bogart, GA can enable you to assemble a new system. Let OLIS upcycle the HP 8453 to capabilities far beyond those it had when new. Retire ChemStation and upgrade to OLIS SpectralWorks. This Windows 7/10 program includes software for 2D and 3D analysis of kinetic and equilibrium data. Achieve the full potential of your HP 8453 with OLIS and Quantum Northwest. Contact us for more information.
