A slab gel cassette is formed from generally flat plates welded together along their borders with a gel space between the plates that is open at the top and bottom edges of the plates to expose the opposing ends of a gel in the gel space to buffer solutions in which electrodes are immersed. The plates are shaped such that the weld line does not intersect with the bottom opening of the gel space. Sealing of the bottom of the gel space, which is necessary for gel casting, is achieved by placing a seal-ing strip over the bottom opening with no danger of leakage of the gel solution along a weld line.

Linvention concerne une cassette à plaque de gel formée à partir de plaques généralement plates soudées entre elles le long de leurs extrémités, un espace pour gel entre les plaques étant ouvert au niveau des bords supérieurs et inférieurs des plaques pour exposer les extrémités opposées dun gel se trouvant dans lespace pour gel à des solutions tampons dans lesquelles des électrodes sont immergées. Les plaques ont une forme qui permet à la ligne de soudure de ne pas croiser louverture inférieure de lespace pour gel. La fermeture hermétique de la partie inférieure de lespace pour gel, qui est nécessaire pour mouler le gel, est réalisée en plaçant une bande détanchéité sur louverture inférieure sans quil y ait un risque de fuite de la solution de gel le long de la ligne de soudure.
