Product Information

Safe and easy dispensing of liquids from bottles without compromise
The new Varispenser 2 and Varispenser 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 bottle top dispensers are fully autoclavable for maximized safety in your lab. The Varispenser 2x has a recirculation valve which prevents reagent loss while ventilating.

Safety and chemical resistance

The built-in safety features of Varispenser 2 and Varispenser 2x protect the user from accidental spills and ensure smooth, trouble-free dispenser operation. For use with a wide range of compatible liquids - including corrosive and inflammable liquids, liquids of high viscosity, detergent solutions, foaming liquids, or liquids with high vapor pressure or density - Varispenser 2 and Varispenser 2x have a broad application base in biology, pharmaceutical, chemistry or forensic labs. These bottle top dispenser models can be used with a variety of liquid reagents while providing superior sealing over a wide range of temperatures and viscosities.

Overcome challenges with liquids

Often applications with a high demand on the 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 the risk of contamination.
