8. The system of claim 1 , wherein each riser is configured to: (i) move back and forth between the next step in the series of steps to lift each of the plurality of vessels to an elevation stage adjacent to the ledge of the next step in the series of steps of the transporter; and (ii) transfer each vessel to the ledge of the next step, wherein a height of the elevation stage is greater than a height of the ledge of the next step in the series.

9. The system of claim 8 , wherein a depth of each of the ledges of the steps is configured to decrease through the transporter, with the ledge of a lower step having a depth larger than that of the ledge of an upper step.

10. The system of claim 9 , wherein the steps of the transporter are configured to align each of the plurality of vessels in a single file arrangement to be received by the transfer belt.

11. The system of claim 8 , wherein each ledge and each riser are each configured to hold more than one vessel in a horizontal and longitudinally tandem fashion parallel to the A-side and B-side of the feed bin.

12. The system of claim 8 , wherein the ledge and the riser of each step in the series of steps are configured to bevel away from the feed bin toward a back of the transporter.

13. The system of claim 1 , further comprising an inspection table adjacent to the feed bin, wherein the inspection table is configured to control at least part of the plurality of vessels that enter the feed bin.

14. The system of claim 1 , wherein each of the plurality of vessels includes more than one identifying parameter and wherein the system is configured to feed the plurality of vessels in a random nature and balance a loading of a subsequent system being supplied.

15. The system of claim 1 , wherein the feed bin further comprises a substantially open top and cover panel configured to provide access to the feed bin.

16. The system of claim 1 , wherein the feeding unit comprises a plurality of feed bins, a plurality of transporters, a plurality of transfer belts, or combinations thereof.

17. The system of claim 1 , wherein the system is configured to supply up to 16,000 vessels per hour.

18. The system of claim 1 , wherein the transfer belt is configured to seek a condition state of a downstream process or unit to determine an operating state of the downstream process or unit and request feedback to adjust operating conditions of the transfer belt.

19. The system of claim 1 , wherein the transfer belt comprises a plurality of raised elements configured to aid with moving each of the plurality of vessels along the path of the transfer belt.

20. A method for supplying a plurality of vessels, comprising:

providing the plurality of vessels;

transferring the plurality of vessels to a feeding unit, the feeding unit configured to:

supply a plurality of vessels to an exit position, wherein each of the plurality of vessels is configured to hold a sample, and wherein the feeding unit comprises:

a feed bin, the feed bin being substantially trapezoidal in shape and comprising a bottom surface, a front side, a back side, an A-side and a B-side;
