Luma 40

The Luma 40 is a simple, temperature controlled cuvette holder with four optical ports for a wide range of spectroscopy applications from absorbance, to fluorescence and even laser. The arrangement of the optical ports permits the measurement of fluorescence at 90 degrees to the excitation on either side of the excitation beam. The optical ports on the Luma 40 can also be used when additional access at 90 degrees is required for photochemical studies.

The standard Luma 40 is mounted on a base with a metric hole pattern for mounting on an optical breadboard. We have mounting options compatible with a wide array of spectrophotometers from different manufacturers, or contact us today for a custom mounting solution to meet your experimental needs!

The Luma 40 is ideal for work in temperature ranges from -15 °C to 100 °C. Circulating coolant (usually water) is used to remove heat from the Peltier heat exchanger. The Luma 40 will maintain precise sample temperatures and stir at a steady reproducible rate, with the ability to flood the optics in a controlled gaseous environment while working at lower temperatures to maintain optical clarity. Use the Luma 40 to measure spectra at precisely maintained temperatures, or for temperature ramping, to observe changes with temperature.

Add a Windowed Jacket and purge with dry gas to comfortably run the temperature down to at least -40 °C with pre-chilled coolant. Purchase the extended temperature option and extend the maximum temperature up to +150 °C. Purchase both and turn your unit into the ultimate, do-anything machine with almost 200°C of temperature variability!

It is easy to operate the Luma 40 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.
