Description
Macro cuvettes 7000 µl, 45 x 12,5 x 22,5 mm are optical-glass spectrophotometer cells designed for larger sample volumes and a longer optical path. Each cuvette provides a 7000 µl working volume with a 20 mm path length and external dimensions of 45 x 12,5 x 22,5 mm. Two optical windows and light transmission from 334 to 2500 nm enable absorbance measurements across the visible and near-infrared regions on conventional laboratory instruments. A PTFE lid helps limit evaporation and protect the sample during reading. Supplied singly from manufacturer Witeg, this macro format suits methods that benefit from a 20 mm path and multi-millilitre fill volumes rather than standard 10 mm cells. Optical glass delivers durable day-to-day performance in teaching, QC, and research settings. Net weight is 0,012 kg per piece. Choose these 7000 µl macro cuvettes when extended path length, generous capacity, and a simple two-window geometry are required for quantitative spectrophotometric work.

Questions about Macro rectangular cells 7000 µl
What is this article?
Macro rectangular cells 7000 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.
