Abstract

An improved displacement-type syringe has a housing, a substantially fixed seal, a solid or closed-tip plunger, an internal passageway formed between the housing and the plunger, and at least two ports on the housing with at least one port located at each end of the passageway for the passage of fluids and the elimination of gas. The syringe may be mounted in apparatus over a wide range of fixed inclination angles and remain substantially impervious to gas accumulation.
