ABSTRACT:
An apparatus for efficiently recovering from gel fractionated sample in a short period of time comprises a rotatable vessel which is provided in a tank to be applied with electricity and which is made of dialysis membrane on its side and a reticulate support plate which is fixed inside the vessel independently of and not contacting the vessel. As the vessel is rotated with solvent solution being charged in the tank and the vessel and gel being charged in the reticulate support plate, direct current is passed between the positive and the negative electrodes provided on both sides of the tank. The direction of the current is thereby reversed at every 180.degree. of rotation of the vessel, such that the fractionated sample eluted into the solvent solution by electrophoresis is forced to remain inside the vessel for efficient recovery thereof.
