Description
Flow-through cuvette (compact) type 178.711-OS is a precision optical cell made from special optical glass for spectrophotometric work across the 320 nm to 2500 nm range. It offers a 10 mm path length, Ø 2 mm aperture and 8,5 mm centre height, giving an internal volume of only 30 µl. Two M6 screw connectors with FEP tubing support continuous-flow measurements in all common spectrophotometer models. Thermally bonded rather than glued construction from manufacturer Hellma provides high chemical and thermal resistance and prevents unintended leakage. Selected optical special glass delivers transmission greater than 80 % for accurate, reproducible results. Bevelled edges enable safe, comfortable handling and reduce chipping risk. The cell can be cleaned and reused repeatedly, offering a sustainable laboratory alternative. Manufactured entirely in Germany to EN ISO 9001 and EN ISO 14001, these Hellma® precision cuvettes combine tight path-length accuracy and parallelism for consistent optical performance in routine and research applications.

Questions about flow-through cells (compact) , 178.711
What is this article?
flow-through cells (compact) , 178.711 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.
