Abstract

The syringe can include a cartridge having a first end and a second end, and respective compartments for components of the multi-component material; a static mixer connected to the first end of the cartridge, the mixer having a dispensing outlet; and a plunger assembly that is movable into the syringe cartridge at the second end to dispense material from the first end. A connection between the static mixer and the first end of the syringe cartridge includes a flow-directing mechanism having a venting position in which the cartridge compartments are cut off from the static mixer and are in communication independently with respective venting outlets, and a dispensing position in which the cartridge compartments are in communication with the static mixer and are cut off from the venting outlets.
