ABSTRACT:
A cartridge for high performance capillary electrophoresis is constructed to accommodate a capillary with a flexible length of tubing surrounding it for the passage of a liquid coolant. Connections and fittings in the cartridge permit quick insertion and removal of the capillary and coolant tube so that capillaries of different lengths can be used with the same cartridge. Apertures in the cartridge body permit the capillary and tubing to be looped outside the cartridge so that different lengths can be connected without the need to coil the capillary inside the cartridge body. A removable capillary aligning device is also disclosed, which fits in the cartridge in a fixed orientation and holds the capillary in alignment with lenses if used and a light beam passing through the cartridge.
