Description
ZU2 Union is a 316 stainless steel chromatography union with 1/8'' ports and a defined 0,75 mm bore for controlled fluid passage. The fitting is intended for chromatographic and laboratory fluidic assemblies that use 1/8'' tubing and require a metal union with a specified internal bore rather than a simple full through channel. Its 316 stainless steel construction supports routine solvent and mobile-phase handling in analytical and preparative environments where corrosion-resistant metal fittings are preferred. Supplied as a single piece with a net weight of 0,03 kg, the ZU2 Union is practical as a service spare or system-build component for manifolds, transfer lines, and modular flow paths. From manufacturer Macherey-Nagel, the union aligns with standard chromatography accessory ranges and helps laboratories maintain consistent connection geometry across instruments. Typical use includes joining 1/8'' lines, standardising spare parts inventories, and supporting HPLC or related chromatographic setups that specify a 0,75 mm bore. Clear port and bore definition simplifies selection when matching existing tubing and method requirements without changing the established fluid path design.

Questions about ZU2 Union
What is this article?
ZU2 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.
