Claim 0:
1. An aseptic mixing system for an aseptic process vessel having an inner cavity defining a volume and an upper mouth with an upper mouth diameter, comprising:
a solid inanimate mixer mounted for rotation about a central axis at the bottom of the process vessel, the mixer being generally circular in plan view with a disk-shaped body in which is mounted at least one magnet to enable coupling with a magnetic-drive exterior to the process vessel, the mixer having an overall outer diameter relative to the central axis that is less than the upper mouth diameter of the process vessel to enable passage therethrough, and a plurality of lower grooves formed in a lower face of the disk-shaped body, wherein there are two of the magnets mounted within the disk-shaped body to enable coupling with a magnetic-drive exterior to the process vessel, and the magnets are positioned within two diametrically-opposed cavities open to an underside of the disk-shaped body, and wherein the two diametrically-opposed cavities are offset circumferentially from the lower grooves.
