Abstract
A fluid preparation system has a sealed sterilized fluid circuit with a sealed sterilized container with a conductivity sensor in communication with an interior of said container. Further, at least one sealed connector is adapted for adding fluid to said container, and at least one sealed connector is adapted for removing fluid from said container. The conductivity sensor is contained in a test line in communication with said interior and is adapted to be connected to a source of suction thereby to draw a sample of contents of said container. Furthermore, the test line may have a check valve to prevent ingress of contaminants into said container, and the sealed connector is adapted for adding fluid to said container and may have an inline sterile filter. Furthermore, the system may have a controller that controls pumping actuators.
