Guaranteed compatibility with all National Diagnostics scintillation cocktails, the National Diagnostics bottle-top dispenser has an accuracy of delivery with 0.3% on maximum delivery and a precision better than 0.1% CV. Fitted with an anti-drip safety valve, a feature that guards against drips when the bottle-top dispenser is not in use. A fine adjustment mechanism allows for even greater reproducibility for repeat dispensing. The right-angled delivery spout ensures accurate dispensing into narrow scintillation vials. Unlike other bottle-top dispensers, the National Diagnostics bottle-top dispenser can be disassembled from the pedestal for thorough cleaning. The dispenser comes with 33, 38 and 45mm adapters to fit 1L and 4L bottles.
