ABSTRACT:
A process for sterilizing a solution and thereafter transferring it to a solution container for storage. A sterilizing filter, flexible tubing and the solution container are provided as a pre-sterilized unit with a label indicating that the unit is sterile. A source of solution to be transferred is connected to an inlet of the sterilizing filter, and the solution is sterilized by transferring it from the source and through the sterilizing filter to the container via the flexible tubing. The integrity of the filter is determined by introducing a pressurized gas into the filter and observing through a light-transmissive portion in the sterile unit for gas bubbles, which would indicate a loss of filter integrity and unit sterility.
