Description
VP 125/21 NUCLEODUR PolarTec, 5 µm is a VarioPrep HPLC separation column built for liquid chromatography applications that use polar-modified silica stationary phases. The column has a length of 125 mm and a wider internal diameter of 21 mm, packed with NUCLEODUR PolarTec material at a particle size of 5 µm. An axially adjustable endfitting enables secure connection and practical bed adjustment during installation on compatible HPLC systems. Supplied as one piece per pack, this larger-bore format is oriented toward preparative and scale-oriented separations where higher loading capacity and 21 mm ID hardware are required. NUCLEODUR PolarTec chemistry from manufacturer Macherey-Nagel is positioned for HPLC work that benefits from polar selectivity on silica-based media. The combination of 125 mm bed length and 21 mm internal diameter defines a clear preparative geometry within the VarioPrep range. Laboratories can match the stated dimensions and 5 µm particle size to existing methods, pumps, and detectors configured for wider-bore columns. The product is classified among HPLC chromatography columns and is provided as a single ready-to-use unit. It supports research, process-development, and quality-control environments that need a defined PolarTec VarioPrep column in the 125/21 configuration without additional accessory claims.

Questions about VP 125/21 NUCLEODUR PolarTec, 5 µm
What is this article?
VP 125/21 NUCLEODUR PolarTec, 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 × 2.1 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.
