Laboratory bottle-top dispenser 42200-0000

variable-volume

The mini bottle dispenser is used for quick and easy dispensing of liquids in volumes of either 500 μl or 1000 μl, its standard thread size is 1 inch (26 mm). The output volume can be selected by twisting an adjustment wheel and then operating the centrally mounted plunger. After refilling, the bottle dispenser can be vented through repeated pumping of the piston. The bottle is then ready for repeated use. The bottle dispenser has no metal valves and is made from shatterproof polypropylene with very high chemical resistance. Cleaning can be done by a damp cloth, using soapy water solution if necessary.
