ONiLAB Pipette Pumps,Scientific Pipette Pump 25ml, Red, for Disposable Plastic and Glass Pipettes… | Durable Construction, Smooth Volume Control, Plastic And Glass Pipette Compatibility, Laboratory Applications

This device works perfectly for precision doses.

Work well and of good quality.

I used this pipetter when working in a biochemistry lab. Now it it good to help measure and dispense additive reagents for fuels. Definitely a good price

Could be user error but the pipette tends to get wobbly now and then, just needs a retightening. Other than that it’s accurate and easy to use

Pipette comes loose sometimes, gotta hold it bur great olive, great product

I’m not sure what I expected for the price. I had a hard time getting the glass pipette to seal and stay seated in the rubber end.

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.

The price is good, it's holding up well, and it works as expected. I like how it can be disassembled easily and cleaned. This has become a bit of a workhorse for me and it's more than paid for itself. Shipping was very fast too.

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.
