Disclosed is a mixing device for mixing, in particular, contents of laboratory vessels. The mixing device has a receiving device for receiving mixtures, a drive for setting the receiving device in a mixing movement relative to a chassis in which the receiving device moves on a closed path, and a bearing for guiding the receiving device in the mixing movement. The bearing has at least two supports, each with two bearing areas spaced apart from each other and having at least substantially no translatory and at least two rotational degrees of freedom. One bearing area bears the support at the chassis, and the other bearing area bears the receiving device at the support. The bearing has a guidance device, which guides the rotation of the receiving device relative to the chassis during the mixing movement.

1. A mixing device comprising: a chassis;a receiving device for receiving mixtures and having a drive by means of which the receiving device is set in a mixing movement in a substantially horizontal plane relative to the chassis in which the receiving device moves on a closed path, periodically returning to a specific position in a specific alignment in space, anda bearing which guides the receiving device to reduce deviations from the horizontal plane in the mixing movement, wherein the bearing comprises: at least two supports, each support having two bearing areas spaced apart from each other, the two bearing areas having substantially no translatory and at least two rotational degrees of freedom, wherein one bearing area of each support mounts the respective support to the chassis and the other bearing area mounts the receiving device to the respective support, anda guidance device which guides the rotation of the receiving device relative to the chassis during the mixing movement, wherein the guidance device has at least one web which connects two of the at least two supports, wherein a first and a second hinge joint, both having no translatory and only one rotational degree of freedom, mount the web between the at least two supports and the first and second hinge joints have axes parallel to each other and are rotatable around the axes. 2. The mixing device according to claim 1, wherein the bearing areas are joint bearings. 3. The mixing device according to claim 1, wherein the axes of the first and second hinge joints run centrally between the respective joint bearings of the two supports which are connected by the web and which are mounted at the chassis and at the receiving device by the respective joint bearings. 4. The mixing device according to claim 3, wherein at the positions of the hinge joints, the web encloses the support in a fork-like manner or the support encloses the web in a fork-like manner. 5. The mixing device according to claim 2, wherein the respective centers of rotation of the two joint bearings of one support are equidistant to the respective centers of rotation of the joint bearings of another support. 6. The mixing device according to claim 2, wherein the centers of rotation and/or the axes of rotation of two of the joint bearings mounting two of the respective supports at the chassis are equidistant to the centers of rotation and/or the axes of rotation of the joint bearings mounting the same respective supports at the receiving device. 7. The mixing device according to claim 1, wherein any weight acting on the receiving device is transferred to the chassis only by the supports and not by the drive. 8. The mixing device according to claim 1 further comprising a controllable thermostating or heating element selected from the group consisting of Peltier elements, resistive heating elements and heating films. 9. A method for mixing contents of laboratory vessels, comprising the steps of placing a laboratory vessel with contents on the mixing device according to claim 1, and then starting the mixing device. 10. The method according to claim 9, wherein the temperature of the contents of the laboratory vessel is changed via a thermostating or heating element. 11. The mixing device according to claim 2, wherein at least one of the joint bearings is selected from the group consisting of a universal joint, a ball joint, and a joint area with two bearings spaced apart from each other, each with only one rotational degree of freedom. 12. The mixing device according to claim 2, wherein the respective centers of rotation of the two joint bearings of one support are equidistant to the respective centers of rotation of the respective joint bearings of all supports. 13. The mixing device according to claim 2, wherein all centers of rotation and/or the axes of rotation of the joint bearings mounting their respective supports at the chassis are equidistant to the centers of rotation and/or the axes of rotation of the joint bearings mounting the same respective supports at the receiving device. 14. A mixing device for the contents of laboratory vessels comprising: a chassis;a receiving device for receiving the laboratory vessels for mixing and having a drive by means of which the receiving device is set in a mixing movement in a substantially horizontal plane relative to the chassis in which the receiving device moves on a closed path, periodically returning to a specific position in a specific alignment in space,one or more laboratory vessels to be held by the receiving device and whose contents are to be mixed by the mixing device, anda bearing which guides the receiving device in the mixing movement to reduce deviations from the horizontal plane, wherein the bearing comprises:at least two supports, each support having two bearing areas spaced apart from each other, the two bearing areas having substantially no translatory and at least two rotational degrees of freedom, wherein one bearing area of each support mounts the respective support to the chassis and the other bearing area mounts the receiving device to the respective support, anda guidance device which guides the rotation of the receiving device relative to the chassis during the mixing movement, wherein the guidance device has at least one web which connects two of the at least two supports, wherein a first and a second hinge joint, both having no translatory and only one rotational degree of freedom, mount the web between the at least two supports and the first and second hinge joints have axes parallel to each other and are rotatable around the axes. 15. The mixing device according to claim 14, wherein the axes of the first and second hinge joints run centrally between the respective joint bearings of the two supports which are connected by the web and which are mounted at the chassis and at the receiving device by the respective joint bearings. 16. The mixing device according to claim 15, wherein at the positions of the hinge joints, the web encloses the support in a fork-like manner or the support encloses the web in a fork-like manner.
