Description
Standard cuvette with lid, 20 mm LB Q is a quartz spectrophotometer cell for optical measurements across the ultraviolet and near-infrared window. Built in LB Q quartz, it supports work in the measurement range from 200 to 2500 nm, including UV light, and is therefore suited to absorbance and transmission assays that extend below the glass cut-off. The 20 mm path length provides an extended optical path for dilute samples and quantitative methods that benefit from higher effective absorbance. Each cuvette is supplied with a matching lid to reduce evaporation and airborne contamination during measurement sequences. The pack contains 2 pc(s) for routine laboratory use in research, quality control, and analytical chemistry. These standard cuvettes from manufacturer Labbox form part of the METRIA range and offer a practical format for UV-Vis instrumentation where dimensional consistency and optical clarity are required. With a net weight of 0,061 kg, the set is convenient for bench handling and instrument loading while covering nucleic-acid, protein, and other UV-active determinations as well as visible-range work up to 2500 nm.

Questions about Standard (macro) spectrophotometer cuvette with lid, 20 mm, LB Q, 2 pcs
What is this article?
Standard (macro) spectrophotometer cuvette with lid, 20 mm, LB Q, 2 pcs is the article on this page. Luminix Health distributes Labbox 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.
