Description
Cylindrical cuvette type 120-QS is a precision spectroscopy cell manufactured from high-performance quartz glass for reliable absorbance and transmission measurements across the ultraviolet to near-infrared range. The optical window covers wavelengths from 200 nm to 2500 nm, with a defined path length (layer thickness) of 20 mm and a fill volume of 5600 µl. A PTFE stopper secures the sample and helps limit evaporation during measurement. Thermally bonded rather than glued construction provides strong resistance to temperature and chemicals and reduces the risk of leakage at the joints. Selected high-performance quartz delivers excellent transmission above 82 percent, supporting accurate, reproducible photometric results on common spectrophotometers. Chamfered edges improve handling safety and reduce chipping. The cell can be cleaned and reused as a durable alternative to disposable optics. Produced entirely in Germany by Hellma to EN ISO 9001 and EN ISO 14001 quality and environmental standards, these precision cuvettes emphasise path-length accuracy and parallelism for consistent analytical performance in research and routine spectroscopy 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.
