qpod: temperature-controlled sample compartment external TC 1 Temperature Controller provided without optics
Product Overview

The qpod is a temperature controlled cuvette holder with four optical ports operated through an external controller.

The standard qpod base has 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! Check out the available options below!

With four optical ports at right angles surrounding the cuvette, most applications of the qpod take advantage of fiber optics for transmitting light, though lasers, focused light sources and probes of various kinds may be used. Each of optical ports of the qpod has slit holders to control optical access to the cuvette and a mounting ring, thermally stable and precisely aligned with the cuvette tower for mounting light sources, lenses, filters, polarizers, mirrors, spectrographs, detectors, or whatever components your experiment requires.

The qpod is ideal for work in temperature ranges from -15 °C to 110 °C. Circulating coolant (usually water) is used to remove heat from the Peltier heat exchanger. The qpod 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 qpod to measure spectra at precisely maintained temperatures, or for temperature ramping, to observe changes with temperature.

Purchase the extended temperature option to safely extend operation above 110 °C to 150 °C for all your high temperature experiments.

It is easy to operate the qpod 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.
