Luma 40/8452

Temperature-controlled cuvette holder with four optical ports for the Olis Computerized HP 8452 Diode Array
Product Overview

Use the Luma 40/8452 for absorbance measurements when your experiment requires access at 90 degrees for photochemical activation. It is easy to mount in the open sample compartment of the HP 8452 Diode Array UV-Vis spectrophotometer.

The Luma 40/8452 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 to temperatures as low as -40 °C. (Due to the short stature required to fit the Luma 40 product into the 8452 spectrophotometer, the extended temperature option, which could extend the range lower, is not available for the Luma 40/8452.)

It is easy to operate the Luma 40/8452 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 8452, you can simultaneously use T-App to control the Luma 40/8452.

No matter how you choose to control the Luma 40/8452, 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 Luma 40/8452, 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 Luma 40/8452 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 8452 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 8452 with OLIS and Quantum Northwest.
