Description
Large cuvette 704 is a precision spectroscopy cell made from optical glass for photometric work across the visible and near-infrared range. Configured as product type 704.000-OG (700-OG), it offers a 20 mm path length, a nominal fill volume of 0,006 l and a glass lid, with a usable wavelength window from 360 nm to 2500 nm. High path-length accuracy and parallelism support continuously reproducible readings, while selected optical glass provides transmission greater than 80 % for exact measurement results. The cell body is thermally bonded rather than adhesive-joined, which strengthens chemical and thermal resistance and reduces the chance of liquid escape during use. Chamfered edges allow comfortable, secure handling and help minimise chipping. Designed for spectroscopy laboratories, these large-format cuvettes from manufacturer Hellma are produced entirely in Germany under EN ISO 9001 and EN ISO 14001 and can be cleaned and returned to service for long-term, sustainable use in analytical workflows.

Questions about large cells, 704
What is this article?
large cells, 704 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.
