Abstract:
1. A filtration cell capable of direct sampling of a fluid from a container, the filtration cell comprising: (a) a reservoir to receive the fluid to be filtered, (b) a filter membrane capable of filtering the fluid to provide a filtrate, the membrane being operatively associated with an opening in the reservoir such that fluid is able to flow over the filter membrane, (c) a base to receive the filtrate after it passes through the membrane, the base including a path through which the filtrate is guided to an outlet from the filtration cell, (d) a container connection supported in the filtration cell adapted to establish fluid communication between a container holding the fluid to be filtered and the reservoir, the container connection including a hollow interior in open communication with the reservoir and adapted to be in open communication with an interior of the container, and (e) a flow channel extending between the container connection and the reservoir such that the hollow interior of the container connection is in communication with the reservoir through the flow channel, wherein the flow channel is open to the filter membrane so that fluid to be filtered can be directly passed from a fluid container over the filter membrane as it is transferred from the hollow interior of the container connection, through the flow channel and into the reservoir, the reservoir being adapted to be pressurized to direct the fluid from the reservoir back to the container.
