Description
Macro cuvettes 14 ml are precision optical cells for spectrophotometric and photometric work in the laboratory. Each cell holds 14 000 µl and offers a 40 mm path length, giving an extended optical path for assays that need larger sample volumes or higher sensitivity. External dimensions of 45 x 12,5 x 42,5 mm fit standard spectrophotometer cuvette holders used in routine analytical setups. Two optical windows made from optical glass provide light transmission across the 334–2500 nm range, covering the visible and near-infrared regions typical of many absorbance and transmittance methods. A PTFE lid is included to limit evaporation and protect the sample during measurement and short standing times. Supplied as a single piece from manufacturer Witeg, these macro cuvettes suit qualitative and quantitative work in chemistry, biochemistry and quality-control laboratories where optical-glass performance is appropriate. The robust macro format supports repeated handling while keeping a consistent optical geometry for reproducible readings.

Questions about Macro rectangular cells 14000 µl
What is this article?
Macro rectangular cells 14000 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.
