Description
Cuvette type 540-QS for scattered light measurements is a precision optical cell made from high-performance quartz glass for spectroscopy across a wavelength range from 200 nm to 2500 nm. The outer diameter is 10 mm with a 10 mm path length, a PTFE stopper and a fire-polished outer cylinder; nominal fill volume is 3,200 µl. Hellma precision cuvettes are thermally bonded rather than cemented, giving high resistance to temperature and chemicals and helping prevent unwanted leakage. Selected high-performance quartz glass supports excellent transmission above 82 % for accurate photometric results. Chamfered edges aid safe, comfortable handling and reduce the risk of chipping. Cells are intended for common spectrophotometers and can be cleaned and reused as a durable laboratory option. Manufacture follows EN ISO 9001 and EN ISO 14001 with high optical standards; a declaration of conformity is available from the manufacturer, with further certificates obtainable on request. This configuration suits scattered-light and related spectroscopic work where dimensional precision, parallelism and reproducible path length are critical for consistent measurement quality.

Questions about cuvettes for scattered light measurements, 540
What is this article?
cuvettes for scattered light measurements, 540 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.
