Brr 20

User-customizable, Temperature-controlled cuvette holder with extended low temperature response and two optical ports
Product Overview

The Brr 20 is a temperature controlled cuvette holder designed for low temperature applications. With optical ports on each side of the cuvette, use the Brr 20 for absorbance measurements or any experiment that can be performed using the 180° beam path.

This standard model has an aluminum baseplate that allows for endless user-customizable mounting options. We also 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! Check out the available options below!

The Brr 20 is ideal for work in temperature ranges from -55 °C to 110 °C. Circulating coolant (usually water) is used to remove heat from the Peltier heat exchanger. The Brr 20 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 Brr 20 to observe absorbance spectra at precisely maintained temperatures, or for temperature ramping, to observe how absorbance changes with temperature.

Purchase the extended temperature option to extend the maximum temperature and turn your unit into the ultimate, do- anything machine with over 200°C  of temperature control from -55°C to 150°C.

It is easy to operate the Brr 20 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.
