ABSTRACT:
A compact device and method for asceptically filling containers eliminates the need for clean work stations. A small enclosure has an outlet opening adapted to fit over and surround the neck of a pre-sterilized bottle. Sterile pressurized gas is introduced into the enclosure which is contoured to force the gas to flow at high velocity through the outlet opening, thereby causing the gas to flow into the bottle and to form a curtain of sterile high velocity gas which surrounds the bottle neck and prevents entry of ambient air. While the gas continues to flow, the bottle is filled with sterile media which passes through enclosure and displaces sterile gas in the bottle while being protected from contamination by the sterile flowing curtain.
