ABSTRACT:
A capillary cartridge for high performance electrophoresis is constructed in two parts--an internal cooling block and an external housing, both constructed to permit sliding of the cooling block within the housing to provide two positions, one of which is a retracted position in which the exposed ends of the capillary, which protrude from the cooling block, are protected by the housing, and the other an extended position in which the exposed ends of the capillary extend beyond the cooling block for access for sample loading and connections to electrode buffers. An improved coolant flow channel inside the cartridge is also included.
