FIELD : chemical industry; other industries; devices for the protein crystals growing.SUBSTANCE : the invention is pertaining to the field of the protein crystals growing and may be used for analysis of the processes of a crystallization and production of the monocrystals of proteins, in particular, in conditions of the microgravitation on the orbital space station. The device for crystallization contains : the crystallization chamber with the located in it settling chamber and the chamber of the crystallization cells, the mechanism of the crystallization process starting-up. The crystallization chamber is formed by the device structure component and the resilient membrane, under which there are the settling chamber, which is made in the form of the cylindrical cavity, in which the settler solution is arranged, and the chamber of the crystallization cells, which is made in the form of annular cavity located concentrically to the settling chamber and containing the seats distributed along the circumference for location of the crystallization cells. The membrane is linked with the gear of start-up of the crystallization process, which ensures the deformed state of the membrane, at which the settling chamber is hermetically blocked by the membrane, and also it is used for the removal of the membrane deformed state to provide communication of the cavities of the settling chamber and the chamber of the crystallization cells. Each crystallization cell contains the crystallization substrate, on which the protein solution is placed, the membrane with the micropores for transit of the vapors of the settlerand this membrane is pressed to the solution of the protein by the rigid perforated diaphragm. Such device is compact and ensures production of the biocrystalline films in conditions of the microgravitation with the minimal risk of the probability of the shift of protein solution during the device delivery to the orbital station and its return back to the earth.EFFECT : the invention ensures production of the biocrystalline films in conditions of the microgravitation with the minimal risk of the probability of the protein solution shift during the device delivery to the orbital station and its return back to the earth.5 dwg |
