The apparatus and method for sterilising caps/stoppers for pharmaceutical purposes comprises a vessel, pump, heater, circulation line. The sterilising liquid (hot water, steam) is heated and pumped to the vessel where a fluidised bed of caps etc. is generated. After leaving the vessel the liquid is circulated/heated. Optionally an additive (siliconisation in case rubber parts) or cooling liquid is added. Further, the vessel is disconnectably attached to the supply lines for transportation to a production facility.
