BioPointe Filter Barrier Tips are now available in both regular polypropylene and the company’s innovative Low Retention material. Together with its traditional diamond polished, ultra smooth mold surfaces, they deliver maximum accuracy and reproducibility when pipetting liquid in microvolumes, resulting in superior pipette tip performance. BioPointe’s Low Retention tips are the product of the company’s extensive experience in resin technology. Through its optimal fluid transfer, these Low Retention products ensure maximum recovery of precious samples and reagents from pipette manipulations. 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 micron 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 – this allows samples to be recovered. CMC-free, non-reactive barriers are manufactured without surfactants, or other extractable components, to precise air-flow standards. All BioPointe pipette tips are universal-fitting, and therefore engineered to fit practically all popular manufacturers of single and multichannel pipettes, so reducing the number of tip brands and styles required in a laboratory.
