Description
O-ring 16 mm for VP guard column holder is a sealing spare part intended for the 16 mm VP guard column holder (718256). It replaces worn seals on the corresponding holder so that the guard-column interface can be restored without exchanging the entire assembly. The pack contains two pieces, providing a convenient stock level for routine maintenance of chromatography systems that use 16 mm VP guard column holders. Dimensionally matched to the specified holder, the O-ring supports laboratories that standardise on this hardware format for column protection. Manufactured by Macherey-Nagel, the part sits within the broader set of chromatography accessories used to keep guard-column setups serviceable. Analytical groups running HPLC and related separation methods benefit from having correct-size seals available when holders are opened for cartridge or frit service. The two-piece pack is suitable for instrument benches and central laboratory stores that maintain VP guard column holder fleets at the 16 mm size.
This article is part of HPLC guard columns, in HPLC columns & accessories.

Questions about O-ring for VP guard column holder 16 mm
What is this article?
O-ring for VP guard column holder 16 mm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC guard columns, inside HPLC columns & accessories, in Chromatography equipment.
A guard column is a short column of the same phase as the analytical column, placed in front of it to catch particles and compounds that would stick forever. It is meant to be replaced. A guard of a different phase changes the separation. The holder and the cartridge are often separate parts.
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.
