The large opening of the BioPointe low retention barrier pipette tips can accommodate large volume funnels, giving easy access to scoops or spatulas.

• Graduation marks
• High performance low retention
• Racked
• Fine point orifice for the highest levels of accuracy and reproducibility
• Universal fit
• Amber to protect light-sensitive materials

BioPointe porous barrier filters in Ultra High Molecular Weight Polyethylene (UHMWPE), block aerosols by coalescing radio-active, chemical, or biological contaminants before they can come in contact with pipettor shafts, and effectively eliminate unwanted signals induced by residual RNA/DNA transferred in trace amounts by aerosol cross-contamination.

The filter is completely inert and consistent in porosity - 20 µm allows the air to pass through, but not any aqueous solutions. It also acts as a safety-barrier against accidental over-pipetting of liquid without risk of sample lock-up.

CMC-free, non-reactive barriers are manufactured without surfactants, or other extractable components, to precise air-flow standards. With its traditional diamond polished, ultra smooth mold surfaces, these tips deliver maximum accuracy and reproducibility when pipetting liquid in microvolumes, resulting in superior pipette tip performance. In addition, through its optimal fluid transfer, low retention products ensure maximum recovery of precious samples and reagents from pipette manipulations.
