Columns for Lab chromatography - Flash Columns

Column PC 04Preparative liquid chromatography columns SEPARCHROM PC04 L and SEPARCHROM PC08 L are intended to replace cartridge columns in flash chromatography applications. High user value is given by advantageous price, possibility to compensate sorbent bed compression and to ability of the column to be refiled.

SEPARCHOM PC04 L columns are made of polypropylene and are compatible with most of organic solvents and with all water solutions. They are equipped with a piston on the input to compensate sorbent bed volume change. The piston is moved by a central screw. Columns have on both sides efficient flow distributors to reach a perfect piston flow of the sample zone. Sorbent is held inside the column by a multilayer polypropylene frit. Piston seal is made of soft expanded PTFE.

Columns are designated for low pressure and medium pressure liquid chromatography. They are delivered either empty or packed with a sorbent according user´s wish ready to be used. They can be simply repacked (sorbents having particle size in the range 20 - 80 µm) using either sedimentation process or dry packing method.

Moving piston of SEPARCHROM PC04 L columns increases their efficiency due an elimination of free space between upper sorbent layer and flow distributor. Columns thus offer perfect separation and in some cases are able to replace high pressure stainless steel columns, mainly when gradient elution is applied.

Flash columns SEPARCHROM PC08 L are equipped with fix end fittings on both ends which nevertheless can slightly press (few centimetres) column bed after packing.
