Abstract
A fluid transfer assembly for single use bioreactors includes a fluid transfer housing that can be mounted to the impeller shaft using a bearing that places the fluid transfer assembly directly below the lowest impeller but allows the impeller shaft to spin inside independently of the fluid transfer assembly. A fluid conduit connects the fluid transfer housing to a port in the single use bag wall which allows fluids to be introduced into the sparger and which also helps prevent the fluid transfer assembly from rotating with the impeller shaft.
