Scienceware® Variable Volume Dispensing Bottles

The Measure-Matic™ variable volume dispensing bottle measures any amount of liquid from 5mL to 25mL repeatedly with this convenient automatic measuring dispenser. A dispensing cup slides onto a delivery tube that is set in a 500mL (16oz) storage bottle. Squeezing the bottle 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 of your measured amount. A hollow stopper serves as a dust cover.

This Bottle Top Reagent Dispenser aids in the transfer of acids and reagents and virtually eliminates accidental bottle breakage and spills by simply squeezing the small plastic bottle. Pressing the pressure release button stops the flow instantly. The pump is easily assembled and installed on 5 pt. (80 fl. oz.) acid bottles, 1/2 and 1-gallon jugs, 2.5- and 4-liter bottles, or any similar bottles with GPI No. 38-430 or 38-400 threaded necks. Two adapters provided for short necks. Bottle not included.
