Patent ID: 7514043

Claim:
A kit for use in conducting crystallization experiments, comprising a pre-filled crystallization plate having a plurality of wells, each well of said plurality of wells being open at an upper end thereof for receiving a crystallization solution, a first level of seal including individual seals recessed within each well at a distance below the upper end thereof for temporarily hermetically sealing the crystallization solution in the wells to allow safe transportation and handling of the pre-filled crystallization plate prior to utilization, and a second level of seal including a sealing surface on said plate above said first level of seal for allowing sealing of said wells above said first level of seal in order to allow vapor diffusion to occur after the individual seals of the first level of seals have been broken, the individaul seals of the first level of seals extending acoss the wells to provide a fluid barrier which retains the crystallization solution in said wells and prevents contact of the crystallization solution with a crystallization surface on which the crystallization is to be carried out.
