50mL Wobble-not Serological Pipet, Individually Wrapped, Paper/Plastic, Bag, Sterile

Wobble-not™ serological pipets have a patented innovative 2-tier step design at the plug end vs. traditional pipets that have a straight cylindrical-shaped plug end, requiring less insertion force.

Wobble-nots are the only serological pipets that will give you two zones of contact in your pipet controller’s nozzle, to increase stability and reduce dripping.
