Laboratory Bottle-Top Dispenser

Safe and effortless liquid dispensation from bottles without any compromise

Master the challenge of difficult liquid dispensing tasks with the universally applicable bottle-top dispensers, Varispenser 2 and Varispenser 2x. The Varispenser 2 and 2x are engineered to consistently dispense selected volumes with no reagent waste, and are available in six distinct sizes to accommodate liquid dispensing volumes ranging from 0.2 to 100 mL. By wiping off the inner cylinder wall during dispensing, the distinctive PFA sealing lip technology prevents crystal building from media residue. The Varispenser 2 and 2x are capable of handling a wide range of liquids, including solvents, acids, and bases, due to their exceptional chemical resistance and this technology.

An additional air vent cap is included to prevent potential contamination from the supply bottle, and a unique thread design and thread adapters guarantee compatibility with the majority of large supply and reagent bottles in the laboratory. The Varispenser 2 and Varispenser 2x are truly safe and convenient for aliquoting liquids, as they feature a 360° rotating valve block that provides safe and easy access in all positions.input:
