Description
Cuvette for reflectance measurements type 692-BF is a precision cylindrical cell made from borosilicate glass for optical reflectance work over the wavelength range 330 nm to 2500 nm. The outer diameter is 65 mm and the fill volume is 110000 µl, with markings at 25 mm and 45 mm corresponding to ISO 17223. Produced entirely in Germany, Hellma cylinder cuvettes are noted for manufacturing precision that supports continuously reproducible measurement results. They are thermally bonded rather than glued, which confers high resistance to temperatures and chemicals and helps prevent unintended leakage of liquids. Specially selected borosilicate glass yields very good transmission greater than 80 % for exact optical results. Chamfered edges allow safe, comfortable handling and reduce the risk of chipping. The cells can be cleaned and reused readily, offering a durable and environmentally considerate alternative for routine laboratory use. Manufacture follows EN ISO 9001 and EN ISO 14001 and meets high optical standards. This single-piece cuvette suits demanding reflectance measurements where dimensional accuracy, chemical durability and reliable transmission are required.

Questions about cells for reflection measurements, 692
What is this article?
cells for reflection measurements, 692 is the article on this page. Luminix Health distributes Hellma (IDL) 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.
