CRYOAPPLICATOR FOR FREEZING BIOLOGICAL OBJECTS

摘要

The cryoapplicator for freezing the biological objects consists of the housing with the lines for direct and reverse flow of cryoagent inside and the tip with the porous structure. The porous structure is designed as the welded disoriented pieces of the copper wire. The porosity percentage and the size of the pores decrease towards the tip. The lower part of the porous structure is designed as the columns with their ridges welded to the internal flat surface of the tip. The width of the base of the porous column is lower than the total width of the lower denser layer of the porous structure. The line of the direct flow inlets directly into the volume of the upper layer of the porous column.
