Description
COD cuvette cooling holder is a metal rack intended to take up to 25 cuvettes for controlled cooling after sample digestion. It supports organised handling of COD vials once the thermal digestion step is finished and before photometric or spectroscopic readout. The stand provides a stable metal framework that keeps multiple digestion cuvettes upright and accessible while they return toward ambient temperature, helping laboratories manage batch workflows without clutter on the bench. Supplied as one piece with a net weight of 0,82 kg and a gross weight of 1,82 kg, the accessory is specified for use with the HI83009800 system and fits routine chemical oxygen demand procedures in water and environmental analysis. This cooling holder from manufacturer Hanna Instruments belongs to the range of spectroscopy-related laboratory articles used alongside digestion blocks and measurement instruments. Its multi-position layout is practical for laboratories that process several COD cuvettes in parallel and need a dedicated place for the post-digestion cooling phase. The metal construction is suited to everyday laboratory use where reliable mechanical support of glass or plastic digestion vials is required after heating.

Questions about Rack for test tube cooling (25 holes)
What is this article?
Rack for test tube cooling (25 holes) is the article on this page. Luminix Health distributes Hanna Instruments 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.
