Luma 40

User customizable Peltier-based temperature-controlled cuvette holder with four optical ports
Product Overview

The Luma 40 comes on a simple base for mounting on an optical breadboard. It has four optical ports permitting measurement of fluorescence at 90 degrees to the excitation on either side of the excitation beam. Use the Luma 40 for normal temperature ranges of -15 °C to +105 °C. Add a Windowed Jacket, purge with dry gas and run the temperature down to at least -40 °C. Purchase the extended temperature option and extend the range up to +150 °C or down to -50 °C. Fluorescence is sensitive to temperature and reliable measurements require the precise temperature control of the Luma 40. Alternatively, take advantage of the additional optical ports and also use the Luma 40 when additional access at 90 degrees is required for photochemical studies. Operate the TC 1/Single Temperature Controller using the menu button, control via program T-App or use the simple text commands of the TC 1/Single to write your own control program.
