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)
• QS indicates that “Quartz Glass High Performance” of the highest purity and homogeneity is used for the window. Because it is made from a silicon compound, it is also called synthetic quartz glass, specially selected quartz glasses are used, which ensure transmission values of more than 82% for a spectral range of 200 to 2500nm for an empty cell
