PURPOSE: To correct the electric current density of migration current and to eliminate temp. irregularty of a gel layer, by providing a sealing part at the legs of a vessel in which gel being a migration supporting material is housed.
CONSTITUTION: The main body of a vessel 1 has lags 3 and a thickness of a gel layer 2 to a bottom part 10 is arranged to be constant and the gel is filled to an opening surfaces 4 of the legs 3. The openings 4 of the legs 3 are sealed around the center in a lengthwise direction of the legs 3. The sealing parts 11 in the center of the legs are not only for increasing the mechanical strength of the legs. By removing the sealing parts 11 and performing an electrophoresis heat dissipation is generated by a cooled part of the open air at the both end parts so that the center part becomes at a high temp. The sealing parts 11 are provided in order to correct the current density at the center part for the purpose of eliminating this temp. irregularity. By such a constitution, a nuniform temp. distribution of the gel layer 2 is performed and an exact split image is obtained.
