Abstract

To avoid internal and external soiling in a device for the metering of chemicals, particularly for seed treatment, a special storage system unit (1) is provided which can be loaded with disposable packages (3a, 3b, 3c) which are connected by means of couplings (13) to a supply line (16) leading to an atomizer (58), in which arrangement a metering unit (41) is arranged in the supply line (16) and the entire liquid-carrying system from the packages (3a, 3b, 3c) to the atomizer (58) is closed off to the working environment.
