Description
Macro cuvettes 17,5 ml are large-volume optical cells intended for spectrophotometric and photometric measurements. With a capacity of 17 500 µl and a 50 mm path length, they provide an extended optical path for methods that benefit from higher sample volumes or longer light paths. The external size of 45 x 12,5 x 52,5 mm is designed for use in standard laboratory spectrophotometer holders that accept macro-format cells. Two windows in optical glass deliver transmission from 334 to 2500 nm, supporting work in the visible and near-infrared spectral regions. Each cuvette comes with a PTFE lid to help reduce sample loss by evaporation and to shield the contents during analysis. Available as one piece from manufacturer Witeg, these cells are suited to chemistry, biochemistry and quality-control applications where optical glass meets the required spectral window. The macro construction supports stable, repeatable positioning and consistent path geometry for reliable absorbance and transmittance data.

What is this article?
Macro rectangular cells 17500 µl 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.
