Abstract
An improved electrophoresis device includes first and second end reservoirs of buffer, and a separation tank between the end reservoirs. The separation tank fluidically interconnects the reservoirs and is configured to hold a stack of gel trays in an oriented electric field and covered by the buffer solution. At least one gas-driven fluid recirculation passage distinct from the separation tank drives buffer in one direction between the reservoirs, and stabilizes the buffer below the level of the trays, while stabilized buffer completes circulation between the stack of trays without thermal or chemical upset of the electrophoresis conditions over time. The device may have the same footprint as a conventional single-tray vessel, while having increased capacity for performing electrophoresis operations.
