PCT No. PCT/IL96/00090 Sec. 371 Date Apr. 23, 1998 Sec. 102(e) Date Apr. 23, 1998 PCT Filed Aug. 27, 1996 PCT Pub. No. WO97/09071 PCT Pub. Date Mar. 13, 1997The present invention provides a method for sterilization of objects including the steps of placing the object that should be sterilized in a closed vessel; placing the closed vessel between two high voltage electrodes; applying a high voltage between the electrodes and converting the oxygen in the air inside the closed vessel into ozone; and keeping the sterilized object inside the closed vessel as long as needed. A "closed vessel" includes also any form of closed container or any closed plastic bag. The closed vessel may or may not have internal electric conductors. Furthermore, the invention provides a device for ozone sterilization of objects for use in the method. The device for sterilization comprises a sterilization chamber; two parallel high voltage electrodes located inside the chamber and connected to a high voltage transformer; a closed vessel with or without internal electrodes located between the two high voltage electrodes and the object to be sterilized is placed inside the vessel; and two parallel insulators located between the two high voltage electrodes and the closed vessel.
