Abstract: A centrifugal fast chromatograph is disclosed. The apparatus includes a rotor, a rotor drive, a plurality of chromatographic columns mounted on the rotor, a transfer disk mounted on the rotor, photodetecting apparatus, a gradient maker and a microprocessor control system. The microprocessor controls and monitors the entire chromatography process. The centrifugal fast chromatograph permits the performance of multiple, rapid, and simultaneous separations.

Abstract: A slab-gel loading system includes a prismatic chamber for filling a plurality of slab-gel holders simultaneously. Each slab-gel holder comprises a pair of spaced apart plates defining an intermediate volume for gel containment. The holders are vertically positioned in the chamber with their major surfaces parallel to the chamber end walls. A liquid inlet is provided at the corner between the bottom and a side wall of the chamber for distributing a polymerizable monomer solution or a coagulable colloidal solution into each of the holders. The chamber is rotatably supported so that filling can begin with the corner having the liquid inlet directed downwardly such that the solution is gently funneled upwardly, without mixing, along the diverging side and bottom surfaces. As filling proceeds, the chamber is gradually rotated to position the bottom wall in a horizontal mode.
