## Description

Material: rubber Color: blue Hole inner dia: 7mm/0.28"; Outer dia: 12mm/0.47" Bulb dia: 3.5cm/1.4"; Total length: 5.5cm/2.2" Suitable for students to use in the laboratory Package included: 5 x pipette dropper rubber bulb

Review: Great for 10ml pipette not for 20ml - 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.
Review: I would buy again. - 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.
