Description
Macro cuvettes 3500 µl, 45 x 12,5 x 12,5 mm are optical-glass spectrophotometer cells for quantitative measurements in the visible and near-infrared range. Each cell holds a sample volume of 3500 µl at a 10 mm path length, with external dimensions of 45 x 12,5 x 12,5 mm. Two optical windows and a stated light transmission range of 334–2500 nm support absorbance work on standard laboratory spectrophotometers. A PTFE lid is supplied to reduce evaporation and limit contamination during measurement sequences. Offered as a single piece from manufacturer Witeg, the macro format is intended for assays that need larger working volumes than micro or semi-micro cells. Optical glass construction provides the mechanical robustness expected in everyday cuvette handling. Net weight is 0,008 kg per piece. These macro cuvettes fit teaching laboratories, routine quality-control spectrophotometry, and general analytical workflows that call for a 10 mm path length together with millilitre-scale fill volumes and a simple two-window optical path.

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.
