Squeezing forces the desired volume of liquid through the tube and into the cup. When pressure is released, excess fluid returns into the bottle for spill free pouring.
• Measure liquids from 5ml to 25ml just by squeezing the bottle
• Polypropylene dispensing cup slides onto a polypropylene delivery tube which is set in a low-density polyethylene 500ml (16 oz) storage bottle
• Hollow stopper serves as a dust cover (included)
