Contact SupplierOur Cuvette (Cells) are manufactured from various types of glass. The most important criterion for the choice of a particular type of glass is the spectral range for which the cuvette is intended. Colored logos are fused onto each Hellma Analytics cuvette, thus indicating the spectral range over which the cuvette can be used.Â
In general we divide the glass materials that we use into two groups, quartz and optical glass. Quartz consists exclusively of silicon dioxide (SiO2) and shows some remarkable properties:Â
» Quartz displays a high UV transmission, in highly purified synthetic quartz down to well below    200 nm.
»The thermal expansion of quartz is extremely low, its coefficient of thermal expansion being 6    x 10-7K-1 between 20 °C and 300 °C.
» Quartz is chemically very resistant and maintains its shape, even at high temperatures up to    approximately 1000 °C.
