Description
EC 250/2 NUCLEODUR PolarTec, 5 µm is an EC HPLC separation column for analytical liquid chromatography. The column measures 250 mm in length with an internal diameter of 2 mm and is packed with NUCLEODUR PolarTec material at a 5 µm particle size, supporting polar and polar-modified reversed-phase separations where stable retention and well-defined peak shapes are important.
This article is part of HPLC columns, in HPLC columns & accessories. See also HPLC guard columns.
Offered as a single unit (1 pc) from manufacturer Macherey-Nagel, this EC-format column fits standard HPLC hardware used in method development, routine analysis, and quality-control laboratories. The 2 mm internal diameter helps limit mobile-phase consumption relative to wider-bore formats while the 250 mm bed length supports higher chromatographic resolution. Approximate net weight is 0,26 kg.
NUCLEODUR PolarTec in the EC 250/2 geometry is intended for laboratories that need a polar-selective HPLC phase in a compact analytical dimension. The column is supplied ready for installation and is suitable for research, pharmaceutical, and industrial analytical workflows that rely on consistent HPLC performance with 5 µm particles.

Questions about EC 250/2 NUCLEODUR PolarTec, 5 µm
What is this article?
EC 250/2 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 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.
