Abstract

A system for combinatorially processing a substrate is provided. The system includes a reactor or chemical library having a plurality of chambers defined within the reactor or library, the chambers operable to mix fluids disposed therein. A drive system is disposed below a bottom surface of the reactor. The drive system is operable to rotate a plurality of support plates below the surface of the substrate. The plurality of support plates has a non-circular shape. The non-circular shape of adjacent support plates includes extensions configured to traverse overlapping regions of rotation during rotation of adjacent support plates. Each of the extensions has a magnet disposed thereon.

Dependent claims

A system for mixing fluids contained in a chemical library, comprising:

a chemical library;
a plurality of plates disposed below the chemical library,
the plurality of plates comprising a first plate and a second plate,
wherein each of the first plate and the second plate has a planer surface,
wherein each of the first plate and the second plate has an axis perpendicular to its planar surface;
wherein each of the first plate and the second plate is configured to rotate around its axis,
wherein each of the first plate and the second plate has a plurality of extensions,
where each of the plurality of extensions has at least one magnet disposed thereon,
wherein the extensions of each of the first plate and the second plate define a region surrounding the plate when the plate is rotated,
wherein the first plate and second plate are adjacent to each other such that the region surrounding the first plate overlaps with the region surround the second plate,
