Abstract
A linear reciprocating actuator for mixing, agitating, separation, continuous sampling and/or harvesting or filtration, gas mixing, and various other applications. The actuator may have a housing closed on one end, and attached to a vessel in a hermetically-sealed manner such that it is part of the fluidic envelope of the vessel. An agitation device may be attached to a shaft which is partially surrounded by the housing, or the agitation device may surround the housing where the housing protrudes into the vessel. The actuator enables agitation of the contents of a hermetically-sealed vessel without mechanical coupling from outside the fluidic envelope of the process. The agitation device is solely acted upon by a magnetic field, is contained entirely within the fluidic envelope of the process, and is not attached to the vessel in any way. The magnetic flux which drives the agitation device passes through the housing.
