Absorbance FLEX Pack CUV
A powerful and flexible spectrometer that fits in the palm of your hand
- For Absorbance Measurements with Cuvettes
- High Fexibility
- Great Performance
- Fully Configurable (including interchangeable slits)
- Optical Resolution better than 1nm
- Low Stray Light
The Absorption Flex Pack CUV is a flexible bundle with all the optical components to perform absorbance and transmittance measurements of solids and solutions using a 10 mm path length standard cuvette holder (for measurements with solids you can use our solid sample holder). This package can be configured for three operational wavelength ranges: UV-Vis, Vis-NIR, and UV-Vis-NIR. All of these configurations provide an optical resolution better than 1 nm (FWHM) within the operational range selected and a fast sample screening with a minimum integration time of 3 ms.
To attain maximum light efficiency, both narrow-range UV-Vis and extended-range UV-Vis-NIR configurations include high-stability UV-Vis-NIR deuterium and tungsten-halogen light source (LS-DW) while the narrow-range Vis-NIR configuration includes a tungsten-halogen light source (LS-W20). The spectrometer included in this bundle is the FLEX RES+, which can be configured a 10 µm slit and a blazed holographic gratings for the lowest low stray light. The Absorption Flex Pack CUV bundle is completed with 200 µm diameter optical fibers.
