BIOREACTOR FOR CULTIVATION OF CELLS ON MICROCARRIERS Russian patent published in 1995 - IPC

FIELD: biotechnology. SUBSTANCE: bioreactor comprises a casing with a magnetic drive and a mixer in the form of a hollow cylinder. The bioreactor is provided with a drop-forming device hermetically sealed on the cover and comprising a casing with a horizontal partition inside which divides said casing into two parts. The lower part of the casing is connected by a pipe with a source of compressed gas. Sealed in said horizontal partition are micropipettes and the bioreactor is also provided with an electropneumatic converter of the control unit for adjusting gas supply into said converter communicating with the atmosphere via a pneumatic throttle. A gas-exchange system is formed by four cylinders with netted walls; said cylinders are located inside the mixer whose upper part has an enlarged portion with holes which communicate with the mixer space along a tangent line. EFFECT: improved design. 2 dwg
