Abstract
A pump includes a seal (70) which comprises a c-shaped sealing element with a sealing lip. The surface of sealing lip is pressed against a piston (8) using a c-shaped spring provided on the opposing surface of the sealing lip contacting a displacement chamber (89). An incompressible filling element is inserted into the spring. Independent claims are also included for the following: (1) dead space adjustment method; and (2) high-pressure chromatography device.
