Patent ID: 8876972

Claim:
A crystallization device for making crystals of a target material from a target material solution which contains the target material to be crystallized, the crystallization device comprising: A) a channel plate including: a) a flat body having a first surface and a second surface; b) at least one elongated channel formed in the body and having one side which extends in a longitudinal direction of the channel, the one side being exposed at the second surface; c) at least one target material solution inlet formed in the body and having one end which opens at the first surface and another end which communicates with a first end of the channel; d) at least one crystallizing solution inlet formed in the body and having one end which opens at the first surface and another end which communicates with a second end of the channel; e) at least one vent hole formed in the body and having one end which opens at the first surface and another end which communicates with the channel at a point between the first end and the second end of the channel; and f) at least one gel inlet formed in the body and having one end which opens at the first surface and another end which communicates with the channel at a point between the second end of the channel and the vent hole; B) at least one first cover sheet covering the first surface so as to achieve an airtight seal over at least an opening of the target material solution inlet, an opening of the crystallizing solution inlet, an opening of the vent hole and an opening of the gel inlet; and C) at least one second cover sheet which is transparent and flexible and covers the second surface so as to achieve an airtight seal over at least an opening of the one side of the channel; wherein the second cover sheet, which is flexible, is configured such that at least a segment thereof can be peeled off to expose at least one crystal which has formed in the channel; and wherein the crystallization device is configured such that the at least one crystal can be picked up from the channel after the at least one segment of the second cover sheet has been peeled off.
