Abstract: A biological component enrichment unit for the isolation, purification and/or determination of a biological component using particles (3) and/or another solid phase, which enrichment unit comprises at least one sample container (1, 15, 26, 32, 39) for the realization of the biological sample method. The enrichment unit comprises a lead-through structure (5), such as a bushing (21, 27) made up of one or several parts or a cover having one or several openings (25, 36). The lead-through structure and one or several sample containers can be brought into connection with one another so that, when the lead-through structure is placed on top of the sample container, a functional unit is formed for the realization of the biological method, such as for the binding of the component, the growing, isolation, purification, enrichment of the bacteria or cell or for another similar method.
