Abstract

A method and apparatus for aspirating and dispensing a sample fluid. The apparatus includes an air source having an output port coupled to a first port of a flow through pressure transducer. A second port of the flow through pressure transducer is coupled to a first port of a sample probe. The flow through pressure transducer provides transducer signals to a detector circuit. In response to the transducer signals provided thereto, the detector detects the occurrence or non-occurrence of a plurality of different events.
