Why can only the bottom part and not the whole of the Eppendorf Research pipette be autoclaved?
The materials/combination of materials used mean that the top part of the Research pipette cannot be autoclaved. The part which comes into contact with the liquid, the bottom part of the pipette, can be autoclaved, however. As the requirement for the top part of a pipette is “cleanliness”, the entire pipette is stable to UV.
