The Varispenser^® 2 and 2x bottle top dispensers offer high chemical resistance and robustness. Varispenser^® 2x is additionally equipped with a recirculation valve for priming the dispensing system without loss of reagent.

The trusted PFA sealing lip technology prevents crystal building from media residue by wiping off the inner cylinder wall during dispensing. This technology combined with the high chemical resistance allows the use with nearly all kinds of liquids. The extra air vent cap with Luer-cone for the assembly of a microfilter prevents possible contamination from the supply bottle.

Both dispensers are completely autoclavable at 121 ºC (2 bar). The 360° rotating valve block offers safe and easy access in all positions. Because of the GL 45 thread on all sizes, Varispenser^® can be used on most common bottle threads in the laboratory.
