ELECTROPHORETIC APPARATUS

PROBLEM TO BE SOLVED: To prevent penetrating of a buffer liquid from a spacer into a gel plate and to simplify mounting or dismounting of the plate at or from an electrophoretic apparatus, that is, a side face of a buffer liquid tank in a longitudinal slab type gel electrophoretic apparatus. SOLUTION: In order to mount a gel plate G in a holder 6, a side edge of a spacer of the plate G is brought into close contact and adjacent in a plane with a protrusion provided at the holder 6. To bring the holder 6 into pressure contact with a side face of a buffer liquid tank, a gasket 14 is interposed so that a close contact adjacent flute becomes a center, and mounted or dismounted by engaging or disengaging Push Latches (trade name) 12, 13 with or from the gaskets 14.
