P20 sterile conductive tips are available for the Biomek NX, NXp, FX and FXp Span-8 systems to take advantage of their liquid level sensing technology. Conductive tips are especially useful when volumes are not always known or specified. It also allows pipetting from the top of the liquid level rather than the bottom of the well or tube, which reduces the tip’s exterior wetted surface to conserve valuable samples and reduces cross-contamination across the deck. These sterile tips include a filter, which reduces the possibility of sample cross-contamination from aerosols. Like all our pipette tips, the P20 tips are made of polypropylene. Guaranteed to be free of DNA, DNase/RNase, PCR inhibition, pyrogen/endotoxin and trace metals. Case of 10 racks.
