For microbiological and other laboratory work in which an active substance is contacted with a substrate there is provided a container for the substrate and a divided carrying body with respective separated sections in sealed contact within the container such that the sections form separate regions with isolated substrate portions in each of the regions. The active substance is supported by the carrying body and is immersed in the respective isolated substrate regions so that it can be diffused into the substrate portions.

Apparatus for carrying out biological and chemical diffusion tests in microbiological, serological, immunological, and clinical-chemical work, in which at least one active substance is contacted with a substrate containing an agent, the reactivity of the agent and active substance being the subject

Apparatus for carrying out biological and chemical diffusion tests in microbiological, serological, immunological, and clinical-chemical work, in which at least one active substance is contacted with a substrate containing an agent, the reactivity of the agent and active substance being the subject of investigation, said apparatus comprising a container containing the substrate, a divided carrying body with respective separated sections in sealed contact within the container such that the sections form separate regions with isolated substrate portions in each of said regions, said carrying body penetrating into said substrate in each of said regions and means supported by said carrying body for introducing said active substance into respective isolated substrate portions where the carrying body penetrates into the substrate by discharging said active substance into the penetrated substrate portions by diffusion whereby the action in said substrate is restricted to said separate regions.
