LC sorbents & bulk packings

LC sorbents & bulk packings are the loose stationary phases used to pack preparative HPLC, flash and open columns in house. Process chemistry, natural product and pharmaceutical development laboratories buy them by the kilogram to scale a separation beyond analytical columns.

Macherey-Nagel supplies all 138 listings. Representative items are the POLYGOPREP silica range in grades 60-12, 100-12, 100-20 and 300-12, each in a 1000 g plastic container, with the grade code distinguishing the variants. Other bulk packings and quantities in the range follow the same format of a named phase plus a pack size.

Choose a packing to match the analytical column you are scaling up from, so retention behaviour carries over, and pick the grade according to the back pressure your preparative system can handle. For packed cartridges rather than bulk material, see the flash chromatography range under Filtration & Sample Preparation. Lancetech Limited quotes multi-kilogram requirements on request.
