Microanalysis device

A device in a gel slab assembly for an electrophoresis system having a gel enclosure which is defined by two plates which are spaced by at least two spacing strips, the device being provided with at least one clamp which is arranged to mutually clamp together the plates in the area of a spacing strip. In the device, each clamp is provided with a web portion and two shank portions. The shank portions include force exerting portions. The shank portions have such an extension that lines between force exerting portions pass through a spacing strip when the clamp is in a mounted position. The force exerting portion of one of the shank portions constitutes a hinge portion for cooperation with a groove-like recess in a supporting frame of the gel slab.
