Pipette Pump Set, 3-Pack

I use these a lot for my chemistry class. They make using a volumetric pipett a breeze. I highly recommend them if you need to pipet a lot

Turns out I only needed the green one, but they work great! Make sure you really jam the pipette in there to get a good seal. I almost feel like Im gonna break it I shove so hard, but that prevents leaking

This pump works great with 10ml pipettes. Smooth precise action and easy use from a relatively inexpensive and easy to clean handheld pump. Works good and can be sterilized.

Great pumps especially for the money, I bought pipettes from other suppliers and they all fit well.

Biggest complaint is that the 25 mL pump can only aspirate 21.5 mL but that's hardly a deal breaker
