Abstract
A crystal forming apparatus and method for using the apparatus, the method including depositing a precipitant solution in a site, incubating the site, during which time volatile vapor evaporates from the precipitant solution and accumulates in the site, and pumping the accumulated volatile vapor away from the site. An exemplary apparatus includes a sealed site except for a vent on the sealed site. In one embodiment, the vent is a passive vent that inhibits vapor diffusion out of the site. In another embodiment, the vent is an active vent that opens in response to a pressure differential. The present invention accelerates and controls the crystal growth process by pumping volatile vapor away from the sealed site.
