Description
VP 250/21 NUCLEODUR 100-5 C8 ec is a VarioPrep HPLC separation column intended for preparative liquid chromatography. It combines a column length of 250 mm with an internal diameter of 21 mm and the NUCLEODUR 100-5 C8 ec stationary phase for reversed-phase work. The design includes an axially adjustable endfitting that supports controlled bed compression and stable packing during operation. Supplied as a single piece, the column suits laboratories that need C8 selectivity for purification, fraction collection, or scale-up from analytical methods. This VarioPrep format from manufacturer Macherey-Nagel is aimed at preparative HPLC systems where moderate sample loads and reproducible octyl-bonded silica chemistry are required. The NUCLEODUR 100-5 C8 ec phase offers a well-known C8 surface for separating moderately polar to non-polar compounds under reversed-phase conditions. With its 21 mm internal diameter, the column supports higher throughput than narrow-bore formats while retaining the separation character of the NUCLEODUR 100-5 platform. It integrates into standard preparative HPLC workflows for method transfer, isolation, and routine purification tasks in research and production support laboratories.

Questions about VP 250/21 NUCLEODUR 100-5 C8 ec
What is this article?
VP 250/21 NUCLEODUR 100-5 C8 ec 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.
