PIPETTE FILLER, black, 3-valve. Consists of a rubber bulb with a capacity of 60 ml (approx).

This is a decent pipette bulb
I have seen stronger bulbs with better vacuum, but this is plenty good enough for non-viscous fluids. The valves are a bit difficult to squeeze for opening, but they don't seem to leak, which is much more important.

Good item, as described
good alternative to a roller pump style pipettor. Easy to learn to use. Use it all the time in lab. Item as described! good purchase.

Great
Not sure why the other comment say it doesn't work. I'm currently using this for my Analytical chemistry lab and it works perfectly, I would recommend to anyone to use a pipette filler over any normal bulb universities/school usually assign.

Wrong color, poor quality
The pipette bulb is not as rigid as standard bulbs. It crumbles and particles fall in the pipette. It is functional, but probably won't last very long. I received a red one instead of the black, which I ordered.

Works great
works great on serological pipettes but takes a bit of time to fill a volumetric pipette due to the water pressure. I find filling the pipette at a diagonal takes less time to fill than straight up and down.

Doesn't work
This device won't hold a pipette. The hole in the bottom has too large of a diameter. It looks ok, but is crap.
