A receptacle has a wall defining a receptacle interior and a shaft housing for guiding a shaft through the wall into the receptacle interior. The shaft housing defines an annular cap with spaced apart inner and outer walls connected by an inner end face facing the receptacle interior. A shaft guide part has an end facing the receptacle interior and an outer surface that defines a gap relative to the inner wall of the shaft housing. The shaft guide part has an annular wall spaced apart from and parallel to its outer surface. The annular wall extends over the free end of the inner wall of the shaft housing and is sealed to the inner and outer walls of the shaft housing by at least one seal each. The shaft guide part is mounted in the shaft housing by a radial ball bearing and by an axial ball bearing.

Receptacle comprising a shaft housing

A bioreactor for culturing microorganisms which has a reactor vessel, a plurality of gas-introduction tubes and a gas-introduction system for introducing gas into a culture medium in the gas-introduction tubes via injectors, wherein the gas-introduction tubes are connected by their respective lower end, in the vertical direction, to the reactor vessel and by their opposite upper end to the upper end of an upright vessel which is likewise connected by its lower end to the reactor vessel, and at the upper end of the upright vessel an expansion vessel is arranged.

Bioreactor for culturing microorganisms

A device and a method for the cultivation of cells is disclosed that utilizes external pneumatic pressure responsive to liquid level sensors to gently recirculate and cause turbulence in cell growth medium to promote cell growth without any shearing action and without a stir motor or mechanical manipulation means.
