Abstract
An aseptic sampling system includes substantially sealed sampling lines connecting one or more sample container to a vessel containing the fluid to be sampled. A flow control system includes valves and/or clamps placed strategically along the sampling lines and filtered vent lines are provided at strategic locations relative to a reversible fluid pump in communication with the sampling lines. The clamps are selectively actuated, the vent lines are selectively opened or closed, and the pump is operated in a forward or reverse direction to permit a volume of sample fluid to be drawn from the vessel and into a sample container and to permit fluid to be purged from the sampling lines either into the sample container or back into the vessel. Thus, sampling and purging can be accomplished without opening the system to potentially contaminating agents and without wasting or having to properly dispose the fluid.
