Foxx Life Sciences, 326-4150, BioPointe Low Retention Racked Filter Barrier Pipette Tips, 10µl, Slim Fit, Extended Length, SterileFeatures:Resin guaranteed bovine-freeFine point orifice for the highest levels of accuracy and reproducibilityCertified free from RNase, DNase and Human DNABioPointe 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. With its traditional 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.Accurate graduation marks provide visual confirmation that the correct liquid volume is being aspirated /dispensed. Perfect fine point orifice for the highest levels of accuracy and reproducibility. All BioPointe tips are universal-fitting, and so engineered to fit practically all popular manufacturers of research-grade single and multichannel pipettes, so reducing the number of tip brands and styles required in a laboratory.Unit of MeasureCase of 960 pcs.
