Luma 40/F2500

Peltier-based temperature-controlled cuvette holder for the Hitachi F-2500 Fluorescence Spectrophotometer
Product Overview

The Luma 40/F2500 is a temperature controlled cuvette holder for the Hitachi F-2500 Fluorescence Spectrophotometer. Use the Luma 40/F2500 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 and extend the range up to +150 °C. Fluorescence is sensitive to temperature and reliable measurements require the precise temperature control of the Luma 40/F2500. The Luma 40/F2500 is mounted on a sample tray of the F-2500 instrument, that must be provided by the customer or purchased from Hitachi. The unit may be controlled using the menu button on the front of the TC 1/Single controller or through program T-App available from Quantum Northwest.
