Attorney, Agent or FirmInternational ClassG01N 27/447 (20060101)AbstractAn improvement in electrophoretic apparatus is provided for non-mechanical fluid transfer between the anode and cathode electrode containing chambers of the apparatus. Buffering fluid is transferred from one electrode containing chamber to the other via gas collecting means and a conduit which extends at a positive angle of include between the electrode containing chambers. By providing a constant and uniform rate of fluid transfer, a uniform pH value is maintained throughout the apparatus without use of mechanical pumps for the duration of the electrophoresis. |
