ABSTRACT:
A micro volume, filtered pipette tip device useful with either of two respective pipettors comprising (i) a manual or electronic, air displacement pipettor operable within the approximate range of 0 to 20 microliters and having a relatively long insert tip, and (ii) a manual or electronic, air displacement pipettor operable within the approximate range of 20 to 200 microliters and having a relatively short insert tip. The filtered pipette tip device includes a pipette tip body having insert and fill chambers extending in continuous tapering configuration from the mounting end to the fluid contacting end. A filter is positioned within the axial bore in the intermediate section, providing a dividing barrier between the insert and fill chambers of the pipette tip device. The insert chamber includes a tapering internal wall structure configured to receive a continuously tapering terminal insert portion of each of the two respective pipettors in a snug, sealed fit within the insert chamber. The filter is positioned sufficiently deep within the axial bore and intermediate section of the pipette tip device to allow the terminal end of the insert portion of either of the two respective pipettors to seat within the insert chamber without contacting the filter means.
