This set of pipette pumps worked well with my glass pipettes. The aspiration was easy to control and the release and final blow was effortless.

Just received these and one of the release handles is broken.they do not come with the stems my bad for not reading it but now I have 3 heads with no stem and one is broken.they did arrive fast.UPDATE!! Tried to use one of the three three that I bought but it wouldn't hold any liquid so I opened it and the seal was cracked so I now have 1 out of three that isnt broken and it's the only one that I dont need or use.do not buy this product!!!!!I would call this dollar store quality but that's an insult to the dollar store.This is the worst purchase I've ever made.

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

I bought this and pipettes specifically for this. Pipettes do not stay in place. Area to install pipettes is a silicone cone basically but with steps. I really think it needs a more secure way to install pipettes as they like to slowly slide out or even pop off.Also disappointed that I thought it would be possible to suck up say 10ml of liquid and then dispense a set amount repeatedly. This is not the case, dispenses completely each time by breaking the suction sometimes leaving a drop or more inside. If it would work like I had hoped, it would be a valuable time saving tool. As it works I can not understand how this is useful at all.Cumbersome to operate. Requires both hands to suck up liquid or more coordination/practice than I had at the time. Did not appear to consistently withdraw the same amount of fluid. Basically it did, but not to the level of precision I would expect. I did limited testing with tap water, showing a discrepancy of several drops.I give 3 stars instead of 1 because it may be user error on operation, but that doesn’t excuse the bad fitting of the pipettes.

This is a great low cost pipette pump. Relatively easy to use, although I wouldn't want to do a lot of repetitive transfers with this. Biggest complaint is that the 25 mL pump can only aspirate 21.5 mL but that's hardly a deal breaker, especially in the under $10 range.
