The Verity Dispenser Dilutor (VDD) may be used in combination with any Verity 4000 series syringe pump for stand-alone use. It allows the user to create and manage pipetting protocols that can be performed with the syringe pump, as well as manual control functions to manually perform home and prime functions. The app also contains a titration function to dispense liquid by the click of a button. For the 4220 and the 4260 there is also a continuous function for dispensing a preset volume alternating the aspirate and dispense steps between the two syringes. All the pipetting functions are designed to be controlled through the wand with a remote control button.
