ABSTRACT:
An electrophoresis apparatus for use with horizontally disposed separation media is disclosed, comprised of a housing with lid, and removable components capable of applying an electric potential across a horizontally disposed medium, the components adapted for electrification by plugless electrical connections each of which establishes firm electrical contact with a power supply upon mere placement of the components in the housing. In its various embodiments, the apparatus is adapted to apply the potential through the use of electrified buffer solutions, electrified wires for placement in direct contact with the separation medium, or both. Spring-loaded contacts on either the buffer solution receptacles or the electrified wires mate with exposed power strips in the housing to form the connection. In the case of the electrified wires, the latter are mounted on a support to which spring-loaded braces are attached for compression by the lid of the housing when closed, such that even pressure is exerted by each wire against the separation medium along the full length of contact, regardless of the position of the separation medium in the housing.
