  • Patent number: 9909945
    Abstract: A method adapted to allow aspiration verification of a liquid such as a biological liquid or liquid reagent at low aspiration volumes (e.g., less than 25 ?L). The method includes attempting to aspirate a volume of a liquid into a probe at an aspiration frequency, measuring an aspiration pressure associated with the attempted aspiration of the liquid and providing a measured pressure signal, and filtering the measured pressure signal with a filter. The filter has a passband frequency containing the aspiration frequency and excluding the frequencies of a disturbance causing noise in the measured pressure signal. Apparatus for carrying out the method are provided, as are other aspects.
