Abstract
An apparatus for electrophoretic separation comprising a fixed support structure and a cassette shell which is removably attached to the support device. Within the cassette shell is a basket having symmetrically arranged ribs to secure a capillary tube in a helical configuration. The ribs have notches to receive a loop of the helically wound capillary tube. The notches of the ribs alternate in orientation with respect to the axis of the helically wound capillary tube. A quarter-turn locking member provides electrical, optical and coolant fluid communication between the cassette shell and the support device.
