The frame comprises two small bars (1, 2) spaced apart by two pairs of elastic blades (3, 4) and (5, 6). Cams (11, 12) load these blades to bring the small bars (1, 2) near each other. The membrane is then fastened under the small bars (1, 2) and a gel is poured onto the membrane. The cams are brought into a position in which they cease to load the elastic blades, and this has the effect of allowing the small bars (1, 2) to move apart from each other, stretching the membrane for supporting the gel. Application to the preparation of gel/membrane assemblies for the production of electrophoretic migration spectra of macromolecules. <IMAGE> |
