<p>An apparatus (10) for processing radionuclides which generally includes a reaction vessel (12) and a block (24). The reaction vessel (12) includes a test tube (14) and a cover (18) secured to a top portion (16) of the test tube (14). The cover (18) defines at least one opening for receiving an input tube therethrough such that raw materials, reagents, gases and products can be introduced into or removed from the test tube (14). The block (24) defines a vessel receptacle (26), an upper temperature changing means (94) and a lower temperature changing means (96). The vessel receptacle (26) defines an upper zone (28) and a lower zone (38) and is configured to receive the reaction vessel (12) therein in a manner such that an upper zone space (36) is defined between an exterior (15) of the reaction vessel (12) and an inner wall (27) of the receptacle (26) in the lower zone (38). The upper temperature changing means (94) serves to alter the temperature of gas in the upper zone space and the lower temperature changing means (96) serve to alter the temperature of gas in said lower zone space (38).</p> |
