[Device for the high-speed cryofixation of biological matter].


A device of simple construction is proposed for rapid cryofixation of biological objects for freeze--fracture studies. The rapid freezing of the object is achieved by it immersion into the fast coolant stream, which is created in a centrifugal rotor of special construction. The freezing rate of the test-object in liquid freon-22 stream is 10 times greater… (More)
