Description
VP 125/21 NUCLEODUR 100-5 is a VarioPrep HPLC separation column measuring 125 mm in length with an internal diameter of 21 mm. The column contains NUCLEODUR 100-5 packing and features an axially adjustable endfitting that enables controlled compression of the chromatographic bed. This longer, wide-bore configuration is intended for HPLC separation tasks that call for the VP 125/21 format and NUCLEODUR 100-5 stationary phase. Available as a single unit from manufacturer Macherey-Nagel, it suits laboratories performing liquid chromatography with VarioPrep column hardware. The axially adjustable endfitting allows fine-tuning of bed packing when solvent systems or operating conditions change, helping preserve packing integrity over the course of use. Length and internal diameter are specified at 125 mm and 21 mm, simplifying matching to methods and system connections. NUCLEODUR 100-5 identifies the packing material filled into this VarioPrep body. Combined with the defined geometry and adjustable endfitting, the column offers a clear hardware choice for HPLC separations configured around these dimensions. Each package contains one column ready for installation in a compatible chromatographic system.

Questions about VP 125/21 NUCLEODUR 100-5
What is this article?
VP 125/21 NUCLEODUR 100-5 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.
