A liquid chromatography system has a reservoir for the mobile phase with a cap which provides for effective control of charging the reservoir with the mobile phase, sparging the mobile phase while it is in the reservoir, feeding the mobile phase to the chromatograph, returning the mobile phase to the reservoir after it has passed through the chromatograph, venting or vacuumization of the reservoir and providing for automatic release of overpressure within the reservoir, all while maintaining the sparged environment in the reservoir.

The assembly tip includes a nozzle which has a cylindrical glass body with a tapered end portion. The non-tapered end of the nozzle is adapted to press fit into one end of a polypropylene collar. The collar has an internal lip, spaced from the end, which functions as a stop. The other end of the collar has an enlarged internal diameter adapted to receive a pipettor.
