Description
Cuvette with tubulature type 221-QS is a precision optical cell made from high-performance quartz glass for reliable spectrophotometric and fluorometric work. It operates across a wavelength range of 200 nm to 2500 nm, offers a path length of 10 mm × 10 mm and provides a filling volume of 3,500 µl. The transition tubulature is fabricated from quartz/Duran. Hellma precision cuvettes are manufactured entirely in Germany and are compatible with all common spectrophotometers. Exceptional path-length accuracy and parallelism guarantee continuously reproducible measurement results. Thermally bonded rather than glued, the cells deliver outstanding resistance to temperature extremes and aggressive chemicals while eliminating the risk of leakage. Selected high-performance quartz glasses ensure transmission greater than 82 % for exact readings. Chamfered edges support safe, comfortable handling and reduce chipping. The reusable design allows thorough cleaning, making the cuvettes a sustainable laboratory choice. Production follows EN ISO 9001 and EN ISO 14001, meeting the highest optical standards.

Questions about cells with tubes, 221
What is this article?
cells with tubes, 221 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.
