ABSTRACT:
A chromatography column piston 14 is adjustable in height within the column tube 4 by means of a friction clamp 22 which furthermore includes a threaded engagement with the associated end cap 8 of the column. As a result, with the friction clamp released the piston rod 16 can be rapidly traversed to or near a desired position, and the clamp then engaged following which cooperation of said threads allows fine tuning of the level of the piston 14 by fine adjustment of the position of the friction clamp relative to the end cap 8.
