Description
Disposable macro cuvettes 4,5 ml PS are single-use optical cells moulded from polystyrene for photometric and spectrophotometric measurements in the macro volume range. Crystal-clear PS construction provides the optical transparency required for visible-range assays at a fill volume of 4,5 ml. Packed in units of 100 pieces, these disposable cuvettes reduce washing effort and the risk of cross-contamination between successive samples. The macro format suits larger sample aliquots typical of routine clinical chemistry, water analysis, quality control and educational laboratory work. Offered by manufacturer Witeg, the cuvettes support high-throughput workflows where convenience and consistent optical quality are important. Polystyrene is a standard material for disposable cells intended for measurements outside the deep ultraviolet. The pack net weight is 0,256 kg. These clear PS macro cuvettes give laboratories a practical single-use option for everyday photometric applications.

Questions about Disposable cuvettes Makro 4,5ml PS
What is this article?
Disposable cuvettes Makro 4,5ml PS 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.
