Description
Cylindrical cuvette type 120-QS made from High Performance quartz glass is designed for spectroscopy across the wavelength range 200 nm to 2500 nm. Path length is 1 mm, filling volume is 280 µl and the cell is fitted with a PTFE stopper. Hellma® precision cuvettes from manufacturer Hellma (IDL) are thermally bonded rather than glued, giving high resistance to temperature and chemicals and preventing unintended leakage of liquids. Selected High Performance quartz glasses provide excellent transmission greater than 82 % for accurate, reproducible measurement results. Chamfered edges enable safe, comfortable handling and minimise the risk of chipping. The cuvettes are manufactured entirely in Germany, suit all common spectrophotometers and can be cleaned and reused for long-term sustainable use. Production follows EN ISO 9001 / EN ISO 14001 and meets high optical standards. Net weight is 0,0035 kg. Highest precision in path-length accuracy and parallelism supports continuously reproducible spectroscopic data in analytical laboratories.

Questions about cylindrical cells, 120
What is this article?
cylindrical cells, 120 is the article on this page. Luminix Health distributes Hellma (IDL) for laboratory use. It sits in Cuvettes, in Labware.
A cuvette is an optical cell. The spectrophotometer or photometer sends a beam through a defined path length, usually 10 mm, and the absorbance is read from that path. Glass is for the visible range. Quartz or a UV-grade plastic is required below about 320 nm, because ordinary glass absorbs there. The path length and the wavelength window are the two numbers that choose the cell. The optical methods that use it sit with NIST and the BIPM. Laboratory ware is indexed under ISO laboratory apparatus.
