Abstract
An apparatus for operatively connecting an electrophoresis capillary tube to a housing assembly, wherein the connecting involves fluid, optical and electrical communication. A capillary cassette is removably fixed to the housing assembly and a detector door is pivoted into place to provide vacuum, electrical ground and optical detection of electrophoretic migration at an outlet end of the capillary tube. The vacuum connection is actuated by a cam mechanism which converts the pivoting motion of the detector door into a reciprocating motion of a vacuum connector which is selectively received within the capillary cassette. The cam mechanism includes an arcuate groove on the detector door, a fixed linear slot and a coupling of the vacuum connector, the arcuate groove and linear slot.
