Description
Macro cuvettes 3500 µl are UV-quartz optical cells for spectrophotometric measurements that extend into the ultraviolet. The working volume of 3500 µl and a standard 10 mm path length make them suitable for a wide range of quantitative and qualitative absorbance methods. External dimensions of 45 x 12,5 x 12,5 mm match common spectrophotometer cuvette compartments used in analytical laboratories. Two windows fabricated from UV-quartz glass provide light transmission from 170 to 2700 nm, covering deep-UV through visible and into the near-infrared—ideal when samples or solvents require UV transparency beyond ordinary optical glass. A PTFE lid is supplied to limit evaporation and protect the sample during measurement. Offered as a single piece from manufacturer Witeg, these macro cuvettes support chemistry, biochemistry, life-science and quality-control workflows that demand a broad spectral window. The quartz construction and defined 10 mm path length help maintain consistent optical geometry for reproducible results.

Questions about Macro rectangular cells 3500 µl
What is this article?
Macro rectangular cells 3500 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.
