Abstract

Foreliggende oppfinnelse tilveiebringer et apparat og en fremgangsmåte for utvikling av en reagensløsning av svovel- trioksyd i en bærer. Apparatet inkluderer en reagensgenerator som er forbundet med middel for innføring av svoveltrioksyd fra en kilde i reagensgeneratoren, middel for innføring av en bærer, f.eks. et flytende halogenkarbon eller en gass som er ikke- reaktiv med svoveltrioksydet, i reagensgeneratoren, og middel for innføring av oleum i reagensgeneratoren. Svoveltrioksydet, bæreren og oleumet blir bragt i kontakt i reagensgeneratoren for å tilveiebringe en reagensløsning av svoveltrioksyd i bæreren. Dessuten inkluderer apparatet middel for å ta ut oleum fra reagensgeneratoren, og også middel for å ta ut reagensløsning fra reagensgeneratoren. Ved en foretrukket utførelse inkluderer apparatet for utvikling av reagensløsningen også, i tilknytning til reagensgeneratoren, et behandlingsrom for overflatebehandling av det polymere harpiksmateriale, innbefattet medisinske produkter som har polymert harpiks- materiale på utsatte overflater derav.
