ABSTRACT:
The present invention provides an apparatus for generating a reagent of sulfur trioxide in a carrier which includes a reagent generator. The reagent generator has associated therewith means for introducing a source of sulfur trioxide into the reagent generator, means for introducing a carrier such as a liquid halocarbon or an inert gas into the reagent generator, and means for introducing oleum into the reagent generator. The reagent generator also includes means for contacting the sulfur trioxide, carrier, and oleum to provide a reagent of sulfur trioxide in the carrier. Additionally, the system includes means for removing oleum from the reagent generator, as well as means for removing the reagent from the reagent generator. In a preferred embodiment, the system for generating the reagent also includes, in conjunction with the reagent generator, a treatment chamber for the surface treatment of polymer resins including medical products which have polymeric resin material on exposed surfaces thereof.
