Eliminate pipetter barrel contamination with Thermo Scientific™ Matrix™ Filtered Pipette Tips. Rigorously tested to ensure optimum performance, these filtered tips eliminate the risk of cross-contamination from aerosols created while pipetting genomic material, bacterial samples or other precious samples.

  • Stringent testing guarantees filter tips that effectively block aerosols.
  • Hydrophobic polyethylene filter material ensures no particulates contaminate samples.
  • Inadvertent contact with filter will not contaminate sample or result in sample loss.
  • Easy to open packaging maintains product sterility while providing easy access.
  • Hinged lid allows rack to be opened without laying lid on benchtop, helping maintain sterility.
  • Racks are sealed in thick polyethylene bag for sterility, which is easy to open with simple snap-and-tear packaging.

Stringent Filter Testing:

  • Filter must meet certain porosity requirements and must form a complete barrier across face of tip.
  • To ensure defects are not present, two specific tests are performed: mercury intrusion and particle count testing.
  • Mercury Intrusion Testing (QC 13.1 - QC 13.8) ensures the filter itself meets specific aerosol blocking requirements.
  • Particle Count Testing (Test Protocol QAS-0100) ensures filter is effective at blocking aerosols after installation into tip; also ensures proper shape and fit of filter.
  • Every lot of tips is tested by drawing a vacuum of aerosols against the filter and ensuring particles do not pass through.

Recommended for:

  • Bacteriology
  • Gel loading
  • PCR setup
  • Preventing cross-contamination during routine pipetting
