Shown and described here is a process for preserving a dispersion in a metering apparatus, wherein the dispersion is stored in a container (1, 101, 201) which is part of the metering apparatus, wherein an oxidant is introduced into the container (1, 101, 201). Also described are a metering apparatus configured for this process and a use of an oxidant for preserving dispersions.

Dispenser, e.g., for tinting pastes, comprising at least one container with a lid. The lid comprises a compartment for holding a liquid, and an atomizer, such as an ultrasonic fogger, arranged to atomize the liquid from the compartment into a headspace of the container. The liquid can for example be an aqueous solution of a disinfectant.
