1. A fluid movement system for moving a sample fluid comprising:

  • a fluid container, pressure variation means for moving the sample fluid from the fluid container into a chamber under the influence of a pressure applied to the fluid movement system, and timing means for controlling the timing for releasing a pressure in the pressure variation means wherein the pressure variation means comprises a volume-variation means for generating an overpressure and/or an underpressure by adjusting the volume thereof, and wherein the pressure variation means further comprises a resilient member for counter-acting against the volumetric variation applied to the volume-variation means.
