Abstract
A syringe pump for aspirating and dispensing fluids is provided. The syringe pump includes a pump casing having an inlet port and an outlet port, a ceramic piston liner received within the pump casing and a ceramic piston. The liner has an internal bore formed by a cylindrical wall, wherein the cylindrical wall further defines a fluid path between the inlet port and the outlet port of the pump casing. The piston is axially movable within the bore of the piston to urge a flow of fluid between said inlet port and said outlet port via said fluid path.
