  • Pasteur Plast Pipets

    Details

    Pasteur-plast pipets render liquid handling simple and safe. Cross-contamination and carry-over simply cannot occur so that tedious clean-ups are unnecessary. In addition, there is no danger of glass breakage with the resulting danger of infectious material escaping. The pasteur-plast pipets are made of transparent polyethylene. They are inert to biological fluids and most acids. The low affinity of the surface reduces the loss of cells and valuable proteins through binding.

    • soft, elastic bulb
    • unbreakable – thus reduced risk of glass injury
    • burr-free orifice for neat, clean and precise dispensing
    • only external graduated pasteur-plast pipets with clearly visible embossed graduations
    • sterile pasteur-plast pipets are gas-sterilized and individually packaged
    • BSE-free
    • can be used for food
    • made of LD-PE
