Abstract
A method for aspirating a fluid from a sealed container and for dispensing a precise quantity of the aspirated fluid. The method involves standard steps of inserting a probe into the container through the container seal and aspirating bubbles and the selected quantity of fluid into the probe before removing the probe from the container and dispensing the fluid. The method also includes an additional step performed at at least one stage in the method to assure that, before the dispensing operation is performed, sample fluid in the probe extends to the end of the probe without any fluid extending beyond the end of the probe.
