Abstract

A slurry chamber is fastened to and held in coaxial alignment with a chromatography column by a V-band. One end of the column has an end cap and frit. A slurry of fluid and chromatographic media is placed in the column and chamber. A piston is forced through the chamber and into the column by a hydraulic ram to expel the fluid and form a media bed in the column. The slurry chamber is removed, and a split end cap is fastened to the column. A threaded recess in the split end cap receives a split, threaded collet. The collet is tightened until it pushes against the piston with the same force as the ram, at which point the ram is released and the column removed for use.
