ABSTRACT:
Slab gels held on trays are agitated in a staining or fixing solution by an apparatus that includes a tray carrier that holds a stack of slab gel trays, a tank that receives the tray carrier with sufficient excess room to allow the carrier to move back and forth within the tank, and a motor with a crankpin that is connected to the tray carrier in a reciprocating connection that translates the circular path of the crankpin into a linear path of movement of the tray carrier.
