qChanger 6
Discover the qChanger 6: a temperature-controlled cuvette holder designed for absorbance and fluorescence spectroscopy. It delivers precise temperature control from -15°C to 110°C, with built-in stirring for six cuvettes simultaneously. Ideal for laboratories that require rapid, parallel testing under uniform temperature conditions.
AbsorbanceThe qChanger 6 is a six-position, rapid-sliding, temperature-controlled cuvette holder designed for absorbance measurements. Each cuvette position features two optical ports, allowing 180° beam paths for precise optical alignment. The sliding assembly enables smooth transitions between cuvettes mid-experiment while ensuring consistent temperature across all six cells. Integrated stirring provides uniform mixing when required.
Operating from -15 °C to 110 °C, the qChanger 6 delivers exceptional thermal stability using thermoelectric temperature control and a water-cooled heat exchanger. To prevent condensation and maintain optical clarity at lower temperatures, inert dry gas flow is recommended. Failure to use gas at these temperatures may result in condensation, affecting measurements and potentially damaging internal components. Like all Quantum Northwest sample holders, the qChanger 6 provides unsurpassed temperature control, ensuring stable hold temperatures within a fraction of a degree.
Control is straightforward with the TC-1 Temperature Controller, included with purchase. Users can set temperatures, stirring speeds, and ramp rates via the TC-1’s front panel or through T-App, Quantum Northwest’s optional control software. T-App provides features such as real-time plotting, scripting, and direct sample temperature measurement when paired with the Probe/10K sensor. Even without T-App, the TC-1 display provides a direct readout of the sample temperature when using the Probe/10K.
The qChanger 6 integrates with a wide range of spectrophotometers. The standard model mounts easily to both imperial and metric optical breadboards, with additional models available for specific instruments. Browse our available models to find one compatible with your setup. If an existing model doesn’t fit your instrument or only partially meets your application requirements, contact us to explore customization options.
With its rapid cuvette switching, and precise temperature control, the qChanger 6 is ideal for high-throughput absorbance studies and experiments requiring efficient sample transitions. Its seamless integration with spectrophotometers and robust thermal stability make it a reliable choice for demanding laboratory applications.

*The holder's temperature performance depends on the operating environment and setup conditions, which must support proper heat dissipation and condensation reduction. While the listed temperatures are consistently achieved during testing, they are not guaranteed in all environments or setups. Meeting the ideal setup conditions outlined in the product's manual is necessary to achieve specific temperature stages.
**The extended range applies only when all corresponding High or Low customization options are implemented. The higher limit is extended by the High Limit package option, and the lower limit is extended by the Low Limit package option.
