For extra stability during demanding measurements such as fluorescence, Avantes offers the CUV-UV/VIS-TC, an air-cooled temperature-controlled cuvette holder. The temperature can be set anywhere between -15°C and +105°C with an accuracy of 0.15°C

Other features include magnetic stirring, slit attenuation kit, and fused-silica lens systems with SMA fiber-optic connectors. It can be combined with any AvaLight light source or AvaSpec spectrometer to create a powerful measurement system.

The CUV-UV/VIS-TC is available in fluorescence, absorption or combined fluorescence/absorption configurations.

Application areas enabled by the CUV-UV/VIS-TC series include DNA melting and annealing, protein thermodynamics, fluorophore characterization, enzyme kinetics and online thermocycling of biological particles.
