Varispenser 2/2x are the ideal choice for dispensing aliquots of liquid from supply and reagent bottles. Advanced sealing lip technology enables dispensing of nearly all kinds of acids, solutions or bases. Available in 6 sizes for dispensing volumes from 0.2 – 100 mL, these instruments are designed to consistently dispense selected volumes without reagent waste. All Varispenser 2/2x dispensers are fully autoclavable for maximum safety in your lab. The Varispenser 2x is additionally equipped with a recirculation valve for priming the dispensing system without loss of reagent. The 360 ° rotating valve block offers safe access in all positions.
For laboratory tasks with aliquots of aggressive solutions like lyes, acids, bases or solvents taken from large supply and reagent bottles, bottle top dispensers need to be universally applicable and of uncompromising quality. The new Varispenser 2 and Varispenser 2x bottle top dispensers offer high chemical resistance and robustness in the range of volumes up to 100 mL. Varispenser 2 x 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. Varispenser 2 and Varispenser 2x are completely autoclavable. The 360 ° rotating valve block offers safe and easy access in all positions. Because of the GL 45 thread on all sizes, Varispenser 2 and Varipsenser 2x can be used on most common bottle threads in the laboratory. Depending on the chosen size, Varispenser 2 and Varispenser 2x come with 3 or 5 additional thread adapters.
Overcome challenges with liquids.
Often applications with a high demand on aggressiveness of chemical, throughput or sterility require the usage of accessories like a drying tube, filter or variable discharge tube for dispensing from reagent bottles. The choice of the correct accessory for your bottle top dispenser can speed up your workflow and reduce risk of contamination.
