Suitable for use with most laboratory acids, alkalis, organic solvents and scintillation fluids, with the exception of hydrofluoric acid. Variable-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. Dispensers 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.
The PTFE piston is easily removable for cleaning and smooth action. The borosilicate glass barrel is protected with a transparent polypropylene sleeve and can be disassembled from the pedestal for thorough cleaning. The chemical-resistant liquid pathway allows dispensing of a wide range of liquids. Dispensers fit bottles with 30mm necks. Fully autoclavable at 121°C.
Ordering Information: Supplied with 38, 40, and 45mm bottle neck adapters and a calibration certificate. A bottle is not supplied; amber squat bottles with safety side filler necks are sold separately.
