Description
Cuvette with two chambers, type 238-QS, is a precision dual-chamber cell manufactured from high-performance quartz glass for spectroscopy across 200 nm to 2500 nm. Each chamber offers a path length of 4,375 mm and a fill volume of 1000 µl, giving a combined configuration of 2 × 4,375 mm and 2 × 1000 µl; two PTFE stoppers are included. Hellma precision cuvettes are thermally bonded rather than glued, delivering high resistance to temperature and chemicals while preventing unintended leakage. Selected high-performance quartz glass provides excellent transmission above 82 % for accurate, reproducible results. Chamfered edges improve handling safety and reduce the risk of chipping. Produced entirely in Germany by Hellma to EN ISO 9001 / EN ISO 14001 standards, these cells suit all common spectrophotometers and can be cleaned and reused for sustainable long-term laboratory use. Gross weight is 0,03 kg. The dual-chamber design supports comparative or reference measurements within a single compact optical cell.

Questions about cells with two chambers, 238
What is this article?
cells with two chambers, 238 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.
