Description
UV cuvettes with a 4,0 ml macro format are disposable optical cells for spectrophotometric measurements in the ultraviolet and visible range. They provide a path length of 10 mm and light transmission from 220–900 nm, with two optical windows for standard beam geometry. Outer dimensions are 45 x 10 x 10 mm, matching common macro cuvette holders used in laboratory photometers and spectrophotometers. The 4,0 ml working volume supports routine absorbance and concentration assays while the defined 10 mm path length keeps calculations straightforward under Beer–Lambert conditions. Supplied in a plastic pack of 100 pieces from manufacturer Witeg, these UV macro cuvettes are practical for high-throughput workflows, teaching laboratories and quality-control series where single-use cells reduce cross-contamination risk. Net weight of the pack is 0,252 kg. They are suited to aqueous and many organic samples within the stated spectral window and fit everyday analytical chemistry and life-science measurement tasks.

Questions about UV cuvettes 40 ml
What is this article?
UV cuvettes 40 ml is the article on this page. Luminix Health distributes Witeg 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.
