Abstract
A sterilizer comprising an openable enclosure (2,4) for surrounding one or more articles (8A, 8B) to be sterilized, the enclosure being arranged to attenuate microwave radiation such that in use, when the enclosure is irradiated with microwave energy, the microwave field energy throughout the interior of the enclosure is significantly less than that outside the enclosure, and the enclosure including a gas tight cavity (2C, 4C) containing a gaseous charge, the charge being chosen from the group of materials which emit ultraviolet radiation when irradiated with microwave radiation.
Claims6
A sterilizer comprising a double-walled container and a closure, the container being formed from a material which is generally transmissive to radiation at microwave wavelengths and the space defined between the walls being filled with a gaseous charge which radiates in the ultraviolet spectrum when irradiated with energy at microwave wavelengths, and the closure being arranged to extend at least partly into the container adjacent the inner surface of the container, the dimensions of the container and the extended part of the closure being dimensioned to define a gap between the inner surface of the container and the outer surface of the extended part of the closure which is of predetermined size, the size of the gap being chosen to form a microwave choke arrangement.
