5mL Polystyrene Wobble-Not Serological Pipette, RNase and DNase Free, Sterile, Bulk in Resealable Bags, 500/CS

There is no comparison. The Wobble-Not serological pipette is superior in ergonomics and performance.

Traditional serological pipets have a straight cylindrical shape vs. the Wobble-not, which has a two-tiered step design which helps to decrease insertion force, while increasing pipet stability in your controller.

Feel the Difference

You will feel better, and work smarter. No more jamming your serological pipet into your pipette controller. Achieve maximum stability (no wobble) and less dripping with this new, revolutionary design to benefit your health and wellness, as well as your research applications.

With standard serological pipets, there has never been a difference in the plug end design. All require high insertion force (jamming) in an attempt to get the top as high up in the pipet controller nozzle as possible.

You do this to try to get as much stability as possible otherwise, you risk dripping of the liquid you pipette. No matter how hard you jam, there is wobble.
