ABSTRACT:
A method and device for dispensing an aqueous fluid which is desired to be maintained in a sterile condition. The method includes storing a quantity of aqueous fluid such as ophthalmic saline solution in a reservoir within a portable container having an outlet. A porous filter medium is arranged within the container adjacent the outlet, and the aqueous ophthalmic fluid is caused to pass from the reservoir through the porous medium and to the outlet. The porous medium has covalently bonded thereto an antimicrobially effective amount of an organosilicon quaternary ammonium compound which is an organosilane. The organosilane can also be bonded to the inner and outer surfaces of the portable container.
