Turret 4

The Turret 4 is a 4-position, rotating, temperature controlled cuvette holder primarily for use with fluorescence spectroscopy, or any experiment that can be performed using the three window beam path. With three optical ports around each cuvette, light may pass straight through the cuvette with an additional optical port at 90 degrees for photochemical excitation or fluorescence measurements. The rotational turret head provides the ability to change which cuvette is actively being held within the excitation beam path mid-experiment.

The standard Turret 4 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 Turret 4 is ideal for temperature ranges from -15 °C to +110 °C for to up to four cuvettes. Circulating coolant (usually water) is used to remove heat from the Peltier heat exchanger. The Turret 4 will maintain precise sample temperatures and stir all four samples 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 Turret 4 to measure spectra at precisely maintained temperatures, or for temperature ramping, to observe changes with temperature.

It is easy to operate the Turret 4 using the TC 1 Temperature Controller, included in the purchase price. The sample temperature, stirring speed, cuvette position, 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.
