An arrangement for sterilizing objects by using a low-pressure plasma. The arrangement includes an evacuable chamber for holding the objects, which evacuable chamber can be connected to a conduit for gas to be ionized. A high frequency transmitting device with an antenna system is provided for inductive generating of an alternating current plasma in the chamber. The antenna system includes two plasma generating coils spaced apart from each another.

Device for sterilizing objects

Described is a sterilization chamber for sterilizing objects for application in a process in which a vapour composite, composed of water vapour and hydrogen peroxide vapour, is guided without a carrier gas flow into the sterilization chamber in which a vacuum prevails, whereby the vapour composite settles on the surfaces of the objects to be sterilized and on the surfaces of the sterilization chamber in the form of a condensation layer, which is suctioned off by means of further evacuation of the sterilization chamber after a certain reaction time. In accordance with the present invention, the surfaces of the sterilization chamber consist of poor heat-conducting, water-repellent material.

Sterilization chamber for sterilizing objects

In a process for sterilizing objects, the surfaces of the objects are dampened by condensating a steam compound of water and hydrogen peroxide. The steam compound reaches hereby the objects to be sterilized without any additional transport gas flow. Subsequent drying occurs by means of evacuation at a pressure below the boiling points of water and hydrogen peroxide.

Process and apparatus for sterilizing objects

In order to sterilize previously washed containers in an evacuable reactor, a low pressure plasma is generated by a high frequency generator. A microwave generator is also and can be switched on for drying the container before the plasma is ignited.

Process for sterilizing containers

An arrangement sterilizes metal cans with a low-pressure plasma. The necessary reactor is formed by two electrodes Inserted into one another, whereby an annular gap remains for the container sleeve. The metal can is connected electroconductively with the outer electrode. The sterilizing plasma can hereby be ignited between the inner electrode and the inner surfaces of the metal can.

Arrangement for sterilizing a container with low-pressure plasma

In order to sterilize the inner surfaces and the outer surface area located in the area of a filling opening of pressure sensitive non-electroconductive containers by means of a low-pressure plasma, an evacuable chamber is provided, which is essentially formed by two electrodes which surround the container.
