    Abstract: Systems and methods for positive dispense verification. In one aspect, a system has a plurality of light emitters. The light from the emitters is directed toward a plurality of light detectors across a proximately horizontal plane. The liquid dispense device is positioned above the horizontal plane of light emission from the plurality of light emitters to the plurality of light detectors such that the dispensed liquid will travel through the horizontal plane defined by the emitted light and onto the container being inoculated. Each of the plurality of detectors is coupled to an amplifier. The amplifier generates a signal in response to an interrupt in the transmission of light from the light emitters to the light detectors when the light path is disrupted by the dispense of liquid confirming the liquid was dispensed onto the container.

    Abstract: A system for automatically processing a biological specimen is provided that includes an elevator comprising a plurality of shelves configured to receive a plurality of sample trays. The trays may comprise a plurality of sample containers containing a sample and having a plurality of respective caps engaged therewith. The trays may further include a plurality of centrifuge tube racks each containing a plurality of centrifuge tubes. The system may include a first transport mechanism, a second transport mechanism and a third transport mechanism. The system may include a chain-of-custody device configured to read identifiers on each of the containers. The system may also include a pipetting device configured to remove a portion from the sample containers and dispense the sample into the centrifuge tubes.

    Abstract: The present disclosure describes pipette tips having an absorbent material (e.g., a flocking material) anchored to a distal end of the pipette tip and related methods of use. In some embodiments, the flocked pipette tips can be used in an automated process and/or system, wherein the contact between the pipette tips and either a sample or a culture medium can be automatically sensed for accurate sample collection and/or dispense. In some embodiments, automatic detection of the liquid interface may be accomplished by detecting a threshold change in capacitance when the pipette tip contacts the sample liquid interface (e.g., for sample collection) or the agar interface (e.g., for sample release). In some embodiments, the automated process and/or system may utilize one or more predetermined, fixed heights for collecting samples and/or depositing samples.
