  • Synthesis reaction column
    Patent number: 5419874
    Abstract: 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.
