ONiLAB Pipette Pump，Set of 3 Lab Pipettes

Work well and of good quality.

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.

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

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.

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

I think I should have spent a bit more for a higher quality one but will keep this as I have a very limited use case for it and won't likely wear this out. It just had a few things that bothered me. the screw nut that tightens the pipette feels a bit flimsy, very flexible, is that good or bad? well it flexes when tightening and binds a bit on the threads so I spend a bit too much force screwing it in, something stiffer and more regid wouldn't have this issue. The wheel requires me to pull up on the plunger to get it started as it's too stiff to get starded with just spinning the wheel, for some reason once I get it going it's fine but once I leave it to sit and take it out again I have to do the same thing, pull on the plunger while spinning the wheel to get it started. UPDATE: It appears they instruct you to lube with silicone grease, fortunately I have some on hand. Haven't used it enough to know if that has made a difference.

I've replaced all those "turkey baster" type balls on the ends of my pipettes with this. It gives so much better control over the extraction process. I think I'll buy a second one.

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

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.
