Zippette variable-volume bottle-top dispensers are suitable for use with most laboratory acids, alkalis, organic solvents and scintillation fluids, with the exception of hydrofluoric acid and some organic solvents.

Valirable-volume bottle-top dispensers feature an anti-drip safety valve, a fine adjustment mechanism for greater reproducibility, an easy-to-adjust calibration mechanism and a right-angled delivery spout for accurate dispensing

The PTFE piston has a smooth action and is easily removable for cleaning. The borosilicate glass barrel is protected with a transparent polypropylene sleeve and can be disassembled from the pedestal for thorough cleaning. The chemically resistant liquid pathway allows dispensing of a wide range of liquids. Zippettes fit bottles with 30 mm necks and they come complete with adapters that will allow mounting on most laboratory bottles. Fully autoclavable at 121°C.

All Zippettes have an accurate delivery within ±0.3% (on maximum delivery) and a precision within 0.1%. The precision valve mechanism ensures easy priming and minimum waste with no leakage back into the reservoir.
