Abstract

An apparatus for the production of biocatalyst beads comprises an immobilization vessel (10) which is provided at its lower end with discharge pipes (23) which extend through a pressure chamber (25) in which a gas pressure prevails. The pressure chamber (25) is terminated by a plate (24) exhibiting holes which coaxially surround the discharge pipes (23). At the lower end of the immobilization vessel (10) is provided a connecting nozzle (30) which is connected in germproof sealing manner to the wall of a collecting vessel (11) which contains a solution of a cross-linking agent or a reprecipitation bath. The collecting vessel (11) may be constructed as a fermenter and provided with an agitator. Both of the vessels may be jointly sterilized.
