Description
O-ring 8 mm for VP guard column holder is a sealing spare part designed for the 8 mm VP guard column holder (718251). The ring restores the sealing interface of the holder when the original O-ring shows wear, helping maintain a reliable connection in chromatography guard-column assemblies. Supplied as a pack of two pieces, it gives laboratories a ready reserve for scheduled maintenance or unplanned replacement during instrument upkeep. This accessory is intended for users of VP guard column holders who need dimensionally matched seals rather than full holder replacement. From manufacturer Macherey-Nagel, the 8 mm O-ring belongs to the chromatography accessories range used alongside analytical column-protection hardware. Keeping matching O-rings on hand supports continuous operation of HPLC and related separation systems where guard columns protect the analytical column. The compact pack format suits both central stores and bench-level spare kits in analytical laboratories that standardise on VP holder geometries.
This article is part of HPLC guard columns, in HPLC columns & accessories.

Questions about O-ring for VP guard column holder 8 mm
What is this article?
O-ring for VP guard column holder 8 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.
