An electrophoresis running tank assembly includes a running tank and a power supply holder that is integral to the running tank. A lid is configured for covering the tank, with two activation arms depending downwardly from the lid and with peripheral vertical skirts of the lid overlapping the walls of the tank. Two switches are held by a switch assembly in the power supply holder and are accessible through a space between the power supply holder and a pin wall that supports two connector pins. When the lid is engaged with the tank, the activation arms extend into the space to abut and thereby close the switches, thereby electrically connecting the switches to the electrode. A power supply can be engaged with the pins to energize the electrodes. Owing to the cooperation between the skirts and the walls of the tank, the lid cannot be tilted relative to the tank to expose the electrodes, but instead must deliberately be lifted up and away from the tank (thus opening the switches and deenergizing the electrodes) to expose the electrodes.

Running tank assembly for electrophoresis

An electrophoresis running tank assembly includes a running tank and a power supply holder that is integral to the running tank. A lid with two pins protruding from it can be engaged with the running tank with the pins extending through holes in the power supply holder. A contact is positioned in each hole, and the contacts are electrically connected to an electrophoresis electrode in the running tank. When a power supply is advanced into the power supply holder and the lid is properly positioned on the running tank, the pins on the lid mate with receptacles of the power supply, thereby establishing a connection between the power supply receptacles and the contacts in the holes and, hence, the electrophoresis electrode.

This invention provides a gel electrophoresis casting cassette for horizontal gel electrophoresis. The tray and lid of the cassette have locking means for securing the two parts to prevent damage to the slab gel and to create slab gels of uniform quality.
