ABSTRACT OF THE DISCLOSURE A multiple gel destaining apparatus is disclosed, in which the gels are laid out horizontally in a series of trays arranged in a stack. Each tray accommodates either one slab gel or one layer of tube gels. The trays are of interchangeable construction, and designed with appropriately placed openings for fluid passage so that destaining fluid flows through the tray stack in a serpentine path, sweeping one tray then sweeping the next in the opposite direction. The tray stack is submerged in a tank with continuous circulation of destaining fluid, arranged to draw the fluid downward through the stack, outward through a filter at the bottom of the tank, and upward along the sides of the tank to the top of the stack. A stacking tray is disclosed which comprises four sides and a base with an elongated opening in the base on one side. A horizontal partition divides the tray into upper and lower portions. There are vertical partitions in the upper portion and baffles in the lower portion, staggered with respect to the vertical partition, to provide an undulating flow for destaining fluid.
