an actuator associated with the socket, the actuator configured to align each magnet with a respective fluid conduit of the processing device.

2. The apparatus of claim 1 wherein the positioning features are positioning pins extending from the socket surface.

3. The apparatus of claim 1 wherein the socket is configured to position the plurality of magnets about 0.001 inches to about 0.020 inches from the processing device.

4. The apparatus of claim 1 wherein the socket is configured to position the plurality of magnets on a cover of the processing device so that the plurality of magnetic contacts is spaced from the processing device.

5. The apparatus of claim 1 wherein the socket is configured to pivot at any angle to position the socket surface relative to the processing device of the cartridge.

6. The apparatus of claim 1 further comprising a hinge attaching a first end of the socket to the housing, the socket surface disposed on or in a second end of the socket.

7. The apparatus of claim 1 further comprising a hinge attaching a first end of the socket to the housing, the socket housing a socket surface positioning member configured to pivot the socket surface at any angle relative to the support surface.

8. The apparatus of claim 1 wherein the support surface includes a temperature controlled plate configured to provide thermal energy to the sample in the plurality of conduits.

9. The apparatus of claim 1 wherein each electrical contact of the socket is spring loaded.

10. A method of aligning a cartridge in a processing system, the method comprising:

supporting the cartridge on a support surface of the processing system, the cartridge including (i) a body having a surface defining one or more cartridge positioning members comprising positioning apertures defined along the cartridge surface, (ii) a sample processing device disposed on the surface of the cartridge, and (iii) a plurality of electrical contact pads associated with the sample processing device, wherein the body of the cartridge defines a plurality of fluid conduits through which a sample flows to and from the processing device;

moving a socket of the processing system proximate to the cartridge and spaced proximate to the support surface, wherein the socket includes (i) a socket surface defining one or more socket positioning members comprising positioning features extending from the socket surface, the positioning features being configured to engage with the positioning apertures, (ii) a plurality of electrical contacts, and (iii) a plurality of magnets, the one or more socket positioning members located in a fixed relation to the plurality of electrical contacts;

engaging the one or more socket positioning members with the one or more cartridge positioning members to align the plurality of electrical contacts of the socket with the plurality of electrical contact pads of the cartridge; and

actuating the socket to align the plurality of magnets of the socket with respective fluid conduits of the processing device.

11. The method of claim 10 further comprising receiving the cartridge on a temperature controlled plate of the support surface to provide thermal energy to the sample in the plurality of conduits.

12. The method of claim 10 wherein the socket is configured to position the plurality of magnets about 0.001 inches to about 0.020 inches from the processing device.

13. The method of claim 10 wherein the socket is configured to position the plurality of magnets on a cover of the processing device so that the plurality of magnetic contacts is spaced from the processing device.

14. The method of claim 10 further comprising pivoting the socket at any angle to position the socket surface relative to the processing device of the cartridge.

15. The method of claim 10 further comprising pivoting the socket at any angle to align the plurality of magnets with the plurality of fluid conduits.

16. The method of claim 10 wherein the processing system includes a hinge attaching a first end of the socket to the housing, the socket surface disposed on or in a second end of the socket.

17. The method of claim 10 wherein the processing system includes a hinge attaching a first end of the socket to the housing, the socket housing a socket surface positioning member configured to pivot the socket surface at any angle relative to the support surface.

18. The method of claim 10 wherein the positioning features are positioning pins extending from the socket surface.
