Descriptions

Hellma Analytics is the world's leading manufacturer of UV/Vis absorption and fluorescence measurement cuvettes/cells used in devices and systems in analytical technology. Hellma Analytics produces a wide range of cuvettes for use in spectroscopy and cytometry with optical path lengths spanning 0.01 to 100mm and above. Thanks to their stability, maximum precision and reliability when used for absorbance and fluorescence measurements, Hellma cuvettes work exceptionally well in a wide range of areas in the lab. With a surface flatness of 1µm, the quartz windows set a benchmark in cuvette production. What's more, the function-optimised design with beveled edges and corners protects against the risk of damage caused by splitting and assists users in their daily work.

Extremely high parallelism of the windows with a maximum tolerance of ±0.01mm

Exceptional optical path length accuracy down to 0.003mm (3µm) for high dimensional accuracy and reproducible measurements results

Unique surface flatness of the optical windows of 0.001mm (1µm)

Very high temperature stability and chemical resistance due to thermal bonding of individual components (effectively monolithic)

OS indicates that "Special Optical Glass" is used for the window; this crown glass, specifically developed for Hellma, is made from exceptionally pure raw materials and gives improved transmission in the near ultraviolet range, an empty cell will give a transmission of more than 80 % over a spectral range from 320 to 2500nm
