A steam steriliser, a single use/disposable container for use in the steriliser and a sterilisation method. The container is a rigid or semi-rigid container having a sealable elongate conduit through which steam sterilant may be introduced into the container and steam sterilant and condensate may be removed from the container. Once one or more items to be sterilised are placed in the container a cover is sealed over the mouth of the container. The steam steriliser has a sterilisation chamber adapted to receive the container and provide sterilant within and around the container. Sterilant is provided to the container via the conduit which is sealed at the end of the sterilisation process.
