A process for capturing at least one radioisotope from a radioisotope solution obtained from a radioisotope source using a radioisotope concentrator device, by fluidly communicating a radioisotope solution from the radioisotope source through a concentrator column to capture the at least one radioisotope in the concentrator column. The waste collecting means using an evacuated vial, and the process fluidly communicating the radioisotope eluate solution to the waste collecting means under a negative pressure. 34a - 40 2 10 32ce. 345 34 34b -- - -- - - - 1 1 -- 120 I, I ,; 114 I' X A
