ABSTRACT:
Pressure equalizing device comprising a fluid container for attachment to a receptacle such as a vial to permit pressure equalization between the fluid container and the receptacle. The pressure equalizing device comprises a flow channel that is arranged to provide fluid communication into or out of the fluid container when the pressure equalizing device is attached to the receptacle. The pressure equalizing device also comprises a fluid inlet that contains a one-way valve that permits fluid to flow into the fluid container via said fluid inlet and that prevents fluid from flowing out of the fluid container via said fluid inlet and filter-receiving means that are arranged to permit fluid flowing into or out of the fluid container to be filtered when the filter-receiving means comprises a filter.
