Cuvette Holders

The CUV-UV/VIS, CUV-FL-UV/VIS and CUV-ALL/UV/VIS are especially designed for absorption and fluorescence measurements and should be used with standard 10x10 mm cuvettes.


For non-standard cuvettes, adjustable ball springs ensure repeatable placement to ensure measurements are taken at the same location. All cuvette holders have a 5 mm wide slot to hold filters and a cover to prevent ambient light from entering the light path.

The CUV-UV/VIS features two AICOL-UV/VIS collimating lenses with adjustable focus to maximise light throughput.


The CUV-FL-UV/VIS has the same specifications, but the collimating lenses are placed under an angle of 90 degrees for fluorescence measurements (to isolate excitation from emission wavelengths). The other two ports on the CUV-FL-UV/VIS have SiO2 coated aluminum mirrors (CUV-FL-MIRROR) to enhance the excitation and fluorescence signals.


The CUV-ALL-UV/VIS features four collimating lenses, all AICOL-UV/VIS, in two optical paths.

For UV measurements, we offers quartz cuvettes. The CUV-10-2 has two optical windows for absorption measurements. The CUV-10-4 features four optical windows, ideal for fluorescence with the CUV-FL-UV/VIS or dual path measurements with the CUV-ALL-UV/VIS.

For low absorption measurements, long pathlength and flow cell cuvettes, the CUV-VAR-UV/VIS cuvette holder is the ideal solution. It features a variable, adjustable path length, ranging from 10-160mm, ensuring maximum flexibility. It can be used as a standard cuvette holder with a 10 mm path length, as a filter holder with 2 mm path length or any path length up to 160 mm. It's supplied equipped with two AICOL-UV/VIS collimating lenses to support applications in the 200-2500 nm wavelength range.
