1. A mixing device having a stirring element, comprising:
a flexible container for receiving fluids and/or solids; and
at least one rotatable stirring element for mixing the fluids and/or solids;
wherein the stirring element comprises a first bearing element and a second bearing element which are arranged at or near opposite ends of the stirring element;
wherein the first bearing element is mounted on a first face of the container and the second bearing element is mounted on an opposite second face of the container;
wherein the first bearing element comprises at least one non-permanently magnetized element in order to be able to be set in rotation by externally induced reluctance forces,
wherein the second bearing element is mounted in a contactless manner by externally induced magnetic forces, and
wherein the flexible container includes at least one cylindrical wall recess which is designed to at least partially receive the second bearing element.
