Abstract

A reaction apparatus has a plurality of reaction flasks whose bottoms can communicate with a sterile gas source and are provided with porous filter plates which permit the gas to flow into the vessel but prevent the liquid from passing out through the plates. The culture flasks are received in pockets on an upper plate of a double-bottom structure which can communicate through the upper plate between a space within the double bottom and the bottom of the culture flasks. The spiral gas feed is connected to the double-bottom space.
