The dispenser outlet (13) is microbiologically sealingly closeable by a valve stopple (25) which closes counter flow direction (11). Outlet 13 is manually reversely opened prior to the pump stroke against a spring (34). The medium reaches outlet (13) via throttles (22, 21, 49). Thus the medium creeps practically non-pressurized to an adhering face (51) of a droplet former (50). There the medium accumulates to a droplet suspending in the upside-down position. The medium contained in the dispenser (1) is effectively protected from germ contamination and the droplet may be simply administered to an eye or the like.
