Description
VP 125/21 NUCLEODUR C18 Pyramid, 5 µm is a VarioPrep HPLC separation column for preparative and semi-preparative liquid chromatography. The column measures 125 mm in length with an internal diameter of 21 mm and is packed with NUCLEODUR C18 Pyramid stationary phase at a particle size of 5 µm. An axially adjustable endfitting supports secure installation and reliable sealing on suitable HPLC hardware. Supplied as a single-piece pack, this format is intended for reversed-phase work where C18 Pyramid selectivity and defined bed geometry are required. Laboratories can use the VP 125/21 configuration for purification, fraction collection, and scale-up from smaller analytical columns while retaining the same phase chemistry. The 5 µm particle bed offers a practical balance of efficiency and operating pressure for many preparative methods. This column from manufacturer Macherey-Nagel fits VarioPrep workflows that call for a robust 125 mm × 21 mm NUCLEODUR C18 Pyramid bed with adjustable endfitting hardware for routine preparative separations.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.

Questions about VP 125/21 NUCLEODUR C18 Pyramid, 5 µm
What is this article?
VP 125/21 NUCLEODUR C18 Pyramid, 5 µm is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC columns, inside HPLC columns & accessories, in Chromatography equipment.
An HPLC column is specified by the stationary phase, the particle size, the length and the internal diameter. A C18, 5 µm, 150 × 4.6 mm column is a different article from a C18, 3 µm, 100 × 2 mm column. The smaller bore belongs on a lower flow. A column has a direction and a pH range.
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.
