Patent ID: 7384603

Claim:
A device for analyzing and archiving a combinatorial library of materials, the device comprising: (a) a first reaction chamber and a second reaction chamber, the first reaction chamber and the second reaction chamber each having a cylindrical upper portion with a diameter and a lower portion with walls defining a tapered polyhedral sink configured to hold at least one spherical building block, with each sink having an upper end; (b) a first feeding channel connected to the upper portion of the first reaction chamber and a second feeding channel connected to the upper portion of the second reaction chamber, the first feeding channel being separate from the second feeding channel; (c) a first discharge channel connected to the lower portion of the first reaction chamber and a second discharge channel connected to the lower portion of the second reaction chamber, the first discharge channel being separate from the second discharge channel; (d) means for identifying the device or the combinatorial library of materials or for identifying the device and the combinatorial library of materials; and (e) a spherical building block in each of the first reaction chamber and the second reaction chamber, with a major portion of the building block disposed within the upper portion of the reaction chamber above the sink and a minor portion of the building block disposed within the lower portion of the reaction chamber in point contact on the walls of the sink, the diameter of the building block being less than 90% of the diameter of the upper portion of the reaction chamber and not less than 70% of the width of the sink at its upper end.
