ABSTRACT Apparatus for delivering samples of liquid to be analyzed in a chromatographic column. The sample is placed in a vial having a compressible plunger slideably mounted therein. The sample is delivered by depressing the plunger with a sampling tip, and the sample is delivered to the tip through a passageway in the plunger. The tip interfits with the plunger to form a fluid-tight seal yet is readily disengaged therefrom. The plunger and the bottom wall of the vial have matching contours which eliminate air from the sample and assure that all of the sample is delivered. A filter mounted in the plunger passageway removes particulate matter from the sample delivered to the tip.
