Preparative columns from Macherey-Nagel feature capillary connections with UNF inner threads 10-32 (1/16”), as with their analytical columns, thus meeting today’s standard in HPLC technology. They are manufactured from stainless steel and are packed with NUCLEOSIL® or NUCLEODUR® packings from range of silicas for HPLC. All packed columns are individually tested and supplied with the corresponding test certificate.
VarioPrep columns have been developed in order to allow compensation of the dead volume, which could result at the column inlet after some time of operation, without need for opening the column. This special column technology is available as columns with one adjustable end fitting at the column inlet and a fixed end fitting at the column end. On request, columns can be supplied with two adjustable end fittings, an option which may e.g. be useful for frequent use of back- flushing techniques. VarioPrep columns are available with lengths of 70, 125 and 250 mm and inner diameters of 8, 10, 21, 32, 40 and 80 mm. VarioPrep guard columns are 50 mm or 70 mm long.
Preparative columns can also be custom-packed with other types of NUCLEOSIL packings as well as with NUCLEODUR silicas. In addition, they can be made in lengths other than those indicated.
