Safe and easy liquid dispensing from bottles without compromise
Master difficult liquid dispensing tasks with the Varispenser 2 and Varispenser 2x universally applicable bottle-top dispensers. Available in six different sizes for liquid dispensing of volumes from 0.2 – 100 mL, the Varispenser 2 and 2x are designed to consistently dispense selected volumes with no reagent waste. The unique PFA sealing lip technology prevents crystal building from media residue by wiping off the inner cylinder wall during dispensing. This technology, combined with their high chemical resistance, allows the Varispenser 2 and 2x to be used for nearly all kinds of liquids, including aggressive solutions like acids, bases or solvents.
A special thread design and additional thread adapters ensure their use with most large supply and reagent bottles in the laboratory, while an extra air vent cap helps prevent possible contamination from the supply bottle. With a 360° rotating valve block offering safe and easy access in all positions, Varispenser 2 and Varispenser 2x really do make aliquoting liquids safe and convenient.
The Varispenser 2x has an additional recirculation valve which prevents reagent loss while ventilating. Both variants are fully autoclavable.
