Description
ZU2L Union is a chromatography fitting with a 1/8'' connection and a 2 mm bore, produced in 316 stainless steel for durable fluid-path joins in analytical laboratory systems. This compact union is intended as accessory hardware for chromatography setups where a defined bore and corrosion-resistant metal construction are required. It is supplied as 1 pc and supports secure tubing connections in HPLC and related separation workflows. The component is offered by manufacturer Macherey-Nagel and originates from the USA. Net and gross weight are each 0,04 kg, with a packaging volume of 0,0000198 m³ and outer dimensions of 0,02 m height, 0,06 m width and 0,02 m depth. Laboratories stock such stainless-steel unions for instrument assembly, maintenance and spare-parts use when a 2 mm bore geometry must be maintained along the flow path. The 316 SS body suits typical solvent environments encountered in chromatographic work. Dual-use classification is not applicable, and the article is non-sterile as supplied. Clear dimensional and material data help match the fitting to existing 1/8'' lines without guesswork.
This article is part of HPLC fittings, tubing & inline filters, in HPLC columns & accessories.

Questions about ZU2L Union
What is this article?
ZU2L Union 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 Chromatography equipment.
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.
