Beschreibung
Zusammenfassung:	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.
