Accessories and Automation for UV/Vis Spectrophotometers

The CuvetteChanger allows efficient automatic measurement of a series of up to 8 cuvettes for both standard measurements with blank subtraction or complex kinetic applications. An external thermostat makes it possible to cool and to heat the cuvettes within a range of 10 – 80 °C.

The UV/VIS Excellence accessories available from METTLER TOLEDO adapt the instrument to users’ specific application requirements. The FillPalMini or CuvetteChanger are automation accessories that can be effortlessly installed with Plug&Play technology and are ready to use instantly.

All accessories, such as cuvettes, sample holders, and automation modules, meet the rigorous manufacturing specifications and therefore contribute to reliable and precise results.

Automated Cuvette Changing

With the CuvetteChanger, a series of up to eight cuvettes can be measured efficiently and automatically for both regular measurements with complex kinetic or blank subtraction applications. Using an external thermostat, the cuvettes can be heated and cooled within a range of 10 °C to 80 °C.


InMotion Autosampler

The InMotion autosamplers have been developed to increase throughput in minimal space and boost productivity without affecting laboratory bench space. Users can select between the InMotion Max, Pro, and Flex, and carry out measurements on up to 303 samples for each series.

Combined with the LabX PC Software, the UV/VIS workstations can be fully customized to the laboratory workflow. The laboratory solution carries out calculations, data management, and reports, thereby saving time for both laboratory managers and operators, and minimizing the danger of transcription errors.


FiberProbe Adapter

UV Vis measurements are made even more efficient, thanks to the FiberProbe Adapter. This adapter fits flawlessly into users’ UV/VIS Excellence spectrophotometer and prevents the necessity for time-intensive sample transfer by bringing the spectroscopic measurement directly to the users’ sample. The InMotion Autosampler offers the ultimate in productivity gain.



CuveT—a Peltier-based, single cuvette thermostat accessory—has been improved to save benchtop space without affecting cooling and heating capabilities. This thermostat unit fits seamlessly on top of the UV/VIS Excellence instrument (UV5Bio, UV5, and UV7) and can be managed with the LabX UV/VIS software, the UV/VIS instrument, or the CuveT terminal.


Automatic Sampling

The FillPalMini automates the sample loading process, pumping the samples rapidly and safely into the flow cuvette. In addition, it can be used for cleaning the cuvette and recovering the samples. With the help of the flow cuvette, UV/VIS Excellence instruments can be incorporated into a multiparameter workstation with a refractometer, density meter, or titrator.


Cuvettes for All Purposes

Both holders and cuvettes are available for an extensive range of applications. These products support different sample volumes, path lengths, and transmittances in both the visible and UV regions.
