Abstract
A device and related method for dispensing liquid. The device includes a housing configured to contain a plurality of liquid dispensing members containing a liquid and configured to contain a receiving member in a receiving position to receive the liquid from the plurality of liquid dispensing members. The housing defines a first pressure chamber and a second pressure chamber. The first pressure chamber is capable of being sealed relative to the second pressure chamber. The device also includes a differential pressure generator operably connected to one of the first and second pressure chambers. The generator is capable of generating a pressure differential between the first and second pressure chambers to cause the plurality of liquid dispensing members to dispense liquid onto the receiving member.
