i just bought REAL glass mohr pipettes... the only thing that sucks about them is the size... my 2 ml pipettes are OVER 13inches long you add the pump on there and they're like 17-20 inches all put together... i also bought a 10ml and 25ml pipetter too for larger quantity mixing.
they're Accurate as hell to + or - .01ml... So i dont know what would "suck" about that... but i can easily reproduce
juice to exact specs. then a little warm water with soap, and a few rinses and they're good to go again.
those little plastic pipettes do SUCK though... they're only good to drip with or refill carts... rest of the time they're garbage. THIS i agree with.
