Luma 40/8454

Temperature-controlled cuvette holder with four optical ports for the Cary 8454 (or HP 8252 or Cary 8453) Diode Array System
Product Overview

The Luma 40/8454 is a temperature-controlled cuvette holder for a single cuvette with four optical ports permitting access at 90 degrees to the absorbance measurement. Optical slits may be used to limit access as appropriate for your experiment. Design your own experiment. Bring laser beams into your sample. Use the Luma 40/8454 for pump-probe experiments or any other experiment in which you wish to access your sample optically at 90 degrees. Easily mount the Luma 40/8454 in the open sample compartment of the Agilent 8454 Diode Array UV-Vis spectrophotometer.

The Luma 40/8454 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 option and run the Luma 40/8454 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.

Operate the Luma 40/8454 using the Agilent ChemStation software (with a Quantum Northwest driver available now as a free download – currently in beta version with free future upgrades), or use the TC 1 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.

Enjoy the power to capture absorbance spectra at precisely maintained sample temperatures, and to observe how sample absorbance changes with temperature. With the Luma 40/8454, 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.
