The lid (3) makes a pressure tight connection with the container (1). Either has connecting bores (8) for supply and removal of nutrient medium and/or oxygen. The lid (3) makes a pressure tight connection with the container (1). Either has connecting bores (8) for supply and removal of nutrient medium and/or oxygen. Cells (7) are cultivated directly or indirectly in or under the lid and/or on the base or a lower cover. The container has an insert on the base, into which the cells are laid. The container has a cylindrical central section, with a lid sealing each end, at threaded connections. The lid is threaded externally, the container internally, or vice versa. A ring seal is included. Supply and removal bores are disposed individually or together in either lid. Lids have a cylindrical extension ring. This partially surrounds and seals onto the cylindrical central section. An external clamping ring completes the seal, or else a threaded and sealing connection is used. A clamping ring acting on container and lids, introduces rolling or rotary motion. The design, its variants and developments are further detailed. Salient features include an internal platform fitting, dual chambers for two cell cultures and a magnetic disc exerting pressure on the cells. The base is a gas permeable membrane. Multiple chambers may be included. |
