The present invention provides a crystallization unit including a solvent reservoir in gaseous communication with a plurality of chambers. Preferably, a plurality of crystallization units are arrayed in the form of a crystallization tray. A first preferred embodiment of the present invention provides a crystallization tray 10 including a rectangular array of crystallization units 26. Each crystallization unit includes a central reservoir 28 and four drop chambers 32 arranged in a cruciform configuration around central reservoir 28. Each drop chamber 32 is connected to central reservoir 28 by a diffusion channel 30. Each drop chamber 32 also includes a shoulder which is capable of supporting a cover slip from which a drop of solution, containing the substance to be crystallized, can be suspended. A second preferred embodiment of the present invention is identical to the first preferred embodiment except that central reservoir 28 is divided into four equal sections by dividers extending vertically from the bottom of central reservoir 28. |
