Abstract

A device for dispensing liquid material is disclosed having an ampoule with at least four storage lumens, a mixing tip coupled to a distal end of the storage lumens, and an outlet lumen in fluid communication with storage lumens via the mixing tip. The at least four storage lumens extend axially along the length of an ampoule body, and the mixing tip has at least four gasket seats formed therein, each gasket seat corresponding to one of the storage lumens. The device also includes a first fluid provided in one of the storage lumens and a second fluid having a characteristic different from the first fluid provided in another of the storage lumens. Each of the storage lumens has a proximal gasket sealing the fluids from a proximal end of the ampoule and a distal gasket sealing the fluids from a distal end of the ampoule.
