Abrégé
(DE)

Begasungsvorrichtung (1) für Bioreaktoren (25) mit einem ersten Begasungselement (3) mit Gasaustrittsöffnungen (36) einer ersten Größe und mit mindestens einem zweiten Begasungselement (4) mit Gasaustrittsöffnungen einer zweiten Größe, dadurch gekennzeichnet, dass die Begasungselemente (3, 4) von einem gemeinsamen Gehäuse (2) mit getrennten Begasungskanälen (7, 8) gebildet werden, dass das Gehäuse (2) als eine ringförmige Scheibe ausgebildet ist, in der die Begasungselemente (3, 4) in einer Ebene angeordnet sind, und dass das Gehäuse (2) ein Unterteil (5) aufweist, in dem die Begasungskanäle (7, 8) konzentrisch zueinander angeordnet und in vertikaler Richtung nach unten von einem Boden (9) des Unterteils (5) begrenzt sind.
