Description
Large cuvette 740 is a precision spectroscopy cell made from optical glass for accurate absorbance and transmission measurements. As product type 740.000-OG it offers a path length of 34,5 mm and a nominal volume of 0,1 l with a 100 ml mark, covering a wavelength range from 320 nm to 2500 nm. Selected optical glass provides transmission above 80 %, supporting exact, reproducible results. Hellma large cuvettes are manufactured entirely in Germany and are thermally bonded rather than glued, giving high resistance to temperature and chemicals and helping prevent unwanted leakage. Chamfered edges enable safer, more comfortable handling and reduce the risk of chipping. The cells can be cleaned and reused, remaining in service over the long term as a durable laboratory option. Production follows EN ISO 9001 and EN ISO 14001 and meets high optical standards for path-length accuracy and window parallelism. Supplied as one piece, this large-format cuvette suits demanding spectroscopic work where stable geometry and reliable optical performance are essential.

Questions about large cells, 740
What is this article?
large cells, 740 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.
