Laboratory Tool 5PCS Blue Suction Ball Pipette Dropper Rubber Bulb, Fit for 3ml 5ml 10ml 15ml Pipettes

Great replacement for my 10ml glass pipette bulb that rotted away. Matches dimensions stated in the description and if you assume the rubber thickness is uniform you can see the maximum volume it will displace is roughly 14ml. Empirically, turns out it will pull 12-13ml pretty easily but unlikely to pull 15ml with it. I’d say 20 isn’t happening and the listing should not say 20ml. Bottom line, if you’re gonna use this with a 10ml pipette or smaller, no problems.

Fit great. Work great. I'm very satisfied.

I'm using these for extracting oil from a jar. A full squeeze of the bulb will suck up about 1 tablespoon of oil.

Hole was to big added zip ties to hold it on and works had suction

WORKED FINE NEEDED SOMETHING LARGER

very small

Purchased to use for priming my lawnmower carburetor (added a straw for convenience). worked perfectly. Only wish that I'd went with a little bigger bulb.

Perfect fit too.
