A baffle assembly (23) positioned between a pipetter assembly (10) and a disposable pipette tip (16) for substantially reducing transfer of aerosol and/or fluid specimens to the pipetter. The baffle assembly (23) includes a barrier structure (25) extending transversely across a receiving chamber (17) of the pipette tip (16) and defines at least one narrow passageway (26) extending generally in the direction of the longitudinal axis (27) through the barrier member (25) between an entrance (30) and an exit (31) thereof. The passageway (26) includes a first wall (32) extending generally transverse, and preferably perpendicular to, the longitudinal axis (27) of the pipette tip to define at least one elbow portion positioned between the entrance (30) and the exit (31) of the passageway. A filter membrane (55) preferably is secured across the passageway (26) to reduce aerosol transport through the passageway (26). A method for substantially reducing transfer of aerosol and/or fluid to the pipetter (10) is also provided, as is a method for securing the filter (55) to the baffle assembly (23).
