Patent ID: 8668878

Claim:
A multi-chamber crystallization plate for crystallization of a sample from a solution, the multi-chamber crystallization plate comprising: a) a plurality of reaction chambers, each reaction chamber of the plurality of reaction chambers comprising: i) a reservoir comprising a first sidewall, a second sidewall, and a floor connecting the first sidewall and the second sidewall; and ii) a ledge formed between an internal surface of the first sidewall and an external surface of the first sidewall, the ledge arranged above the floor of the reservoir, the ledge comprising a crystallization space formed in the ledge, wherein the crystallization space and the reservoir are in fluid communication with each other; b) a flat planar surface comprising a sideways circumferential surface and a plurality of connection spacers, the sideways circumferential surface encircling the plurality of reaction chambers; c) the plurality of connection spacers connecting adjacent first sidewalls and second sidewalls of adjacent reaction chambers of the plurality of reaction chambers; and d) the plurality of connection spacers each comprising a groove having a depth that extends below the flat planar surface.
