Product Information

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.

Wide choice of accessories for all your large volume dispensing needs


A variety of accessories are available for the Varispenser 2 and Varispenser 2x bottle-top dispensers to help you overcome any liquid dispensing challenge you might meet in the lab. Choose from a selection of drying tubes, filters, variable discharge tubes and more to speed up your workflows and prevent contamination. Read more on the right accessories for your bottle-top dispenser in our White Paper No. 38.
