Abstract
A biological macromolecular substances crystallization apparatus comprises a plate-like base, a lid having a concavity which defines an experimental vessel for crystallizing biological macromolecular substances when the lid is put on the base, a groove formed in the base of the experimental vessel for holding a first specimen solution for crystallizing biological macromolecular substances, a trench-like groove formed in the base of the experimental vessel for holding a second specimen solution for crystallizing biological macromolecular substances, tight sealing means for tightly closing the experimental vessel, a plug which is provided in the concavity in the lid, and which is pressed to cover said grooves and to separate said groove from said trench-like groove, and a valve which is provided in the concavity in the lid, and which equalizes an internal pressure in the experimental vessel to an external pressure. Because of the valve for equalizing internal pressure of the experimental vessel to an external pressure, even when volume of the interior of the experimental vessel greatly vary between on standby and in experiments, leakage of the solutions loaded in the apparatus can be…
