Abstract
A cell culturing apparatus having a unitary filter and stirring head suspended within a culture vessel by a flexible conduit which permits movement of the head in a predetermined nonrotary path for stirring the culture medium within the vessel while at the same time permitting filtering and removal of expended medium and culture byproducts by passage through the head and flexible conduit. The flexible conduit has an upper portion fixedly secured to the culture vessel so as to eliminate the necessity for rotary bearings and the like between relative moving parts, and the head carries a magnet which is movable by means of a magnetic drive located outside the culture vessel. In one embodiment, an auxiliary supply line is disposed within the flexible conduit and head to permit the introduction of fluids into the culture vessel simultaneously with the removal of expended medium therefrom.
