The present invention is directed to a synthesis reaction column which can be conveniently implemented in post synthesis procedures. The reaction column is configured to allow easy connection to a syringe and post synthesis reagent container without requiring connection adapters. In one embodiment, the reaction column configured in the form of a cylindrical column containing the solid-phase support and having a narrow bore tube extending at one end. The tube functions as a piercing tip for accessing a septum sealed vial containing post synthesis reagent. In another embodiment, the reaction column is configured in the form of a cylindrical barrel enclosing the solid-phase support and having a threaded mount at one end. To complement the reaction column for post synthesis procedures, a vial having a complementary threaded mount at the opening is used for containing a reagent. This vial is conveniently threaded onto the end of the barrel without adapters. Consequently, post synthesis procedures can be implemented conveniently. Both embodiments may be conveniently connected to the reagent delivery system in an automated instrument for carrying out synthesis procedures, as well as post synthesis procedures.
