A fibrin glue applicator system (10) is provided for dispensing a first and a second protein solution which form a biological adhesive when intermixed on an application site. The fibrin glue applicator system (10) includes a coupler interface (16), a disposable loading unit (DLU) (14), and a housing (12) having a handle portion (20) which includes a trigger (22) operatively associated with a slide bar (36) for dispensing the solutions from the DLU (14). Each piercer (66) is fluid communication with one of the two cylinders (46) of the DLU (14) via a respective conduit (64) connected to a respective main conduit (60). A first one-way valve (68) is included within each conduit (64) to open, and close a path leading from the piercer (66) to the main conduit (60). A second one-way valve (70) is fixed within each main conduit (60) in proximity to each dispensing orifice to open, and close a path leading from each cylinder (46) to its corresponding dispensing orifice.
