Description
Nano screw coupling is a NANOCOLOR connecting piece for joining the sample cuvette to the COD round cuvette in photometric laboratory procedures. It provides a screw-type interface that helps keep the two cuvettes linked during COD-related sample handling, supporting orderly transfer and measurement steps in environmental analysis. The coupling is supplied in a pack of two pieces, so laboratories can keep a spare on hand for routine replacement or parallel workstations. As part of the NANOCOLOR accessory range from manufacturer Macherey-Nagel, it is intended specifically for the sample-cuvette to COD round-cuvette connection rather than as a universal laboratory fitting. This focused design helps maintain compatibility within established NANOCOLOR COD workflows used in water and wastewater testing environments. With a net weight of 0,03 kg, the pack remains light and convenient to store with other small system parts. Non-sterile construction matches typical chemical-analysis bench practice. Using the dedicated screw coupling reduces improvised connections between cuvettes and supports consistent handling when operators prepare or process COD round-cuvette measurements alongside matching sample cuvettes in day-to-day laboratory routines.

Questions about NANO Threaded union (pack 2)
What is this article?
NANO Threaded union (pack 2) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC fittings, tubing & inline filters, inside HPLC columns & accessories, in Chromatographie.
HPLC fittings and tubing are numbered by bore. A wide bore after the column broadens the peaks. Finger-tight and wrench fittings, and stainless against PEEK, are different pressure ratings. An inline filter is the last screen before the column, and it clogs on purpose so the column does not.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
