Varispenser plus 0.5-2.5mL
The best way of taking aliquots of liquid from large supply bottles is by using bottle-top dispensers. The requirements of such a bottle-top dispenser are clear: it must be capable of exact reproducible dispensing that does not waste any reagent. When dealing with aggressive liquids, such as solvents, it must ensure the best possible protection for the users and their laboratory. This safety is guaranteed by the Eppendorf Varispenser®. Their tight seal provides the best possible protection against contact with caustic media, such as solvents, and they are chemically resistant and fully autoclavable for the utmost in safety for you and your lab.
Bottletop dispenser, for external bottle threads of 32mm (sizes 1,2, & 3) or 45mm (sizes 4,5, & 6), complete with telescopic tube, tool and 3 adapters, plus recirculation valve, valve toggle and media-specific fine adjustment.
