Abstract: A unit for rapid priming and flow of liquid through the unit is disclosed. The unit comprises a connector for communicating with liquid in a sealed container, the connector having an exit orifice around which is secured one end of a primer tube. The other end of the primer tube is joined to a pooling conduit. The diameter of the primer tube is greater than the diameter of a drop of liquid released from the orifice and the diameter of the pooling conduit is no greater and preferably slightly less than the diameter of the drop of liquid. Multiple units can be joined to a common tube of enlarged diameter which leads into a pooling and dispensing container.
