An apparatus for processing radionuclides which generally includes a reaction vessel and a block. The reaction vessel includes a test tube and a cover secured to a top portion of the test tube. The cover 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. The block defines a vessel receptacle, an upper temperature changing means and a lower temperature changing means. The vessel receptacle defines an upper zone and a lower zone and is configured to receive the reaction vessel therein in a manner such that an upper zone space is defined between an exterior of the reaction vessel and an inner wall of the vessel receptacle in the upper zone. Likewise, a lower zone space is defined between an exterior of the reaction vessel and inner wall of the vessel receptacle in the lower zone. The upper temperature changing means serves to alter the temperature of gas in the upper zone space and the lower temperature changing means serve to alter the temperature of gas in said lower zone space.
