Abstract: A non-thermal plasma cleaning device including: an enclosure including an input port for fluid connection with a gas supply; a radio-wave source; a controller configured to successively perform, during a cleaning step, at least two, preferably at least three, non-thermal plasma generation cycles each including: controlling the radio-wave source to be in an active state during a first predetermined duration to generating a non-thermal plasma in the enclosure; and controlling the radio-wave source to be in an inactive state during a second predetermined duration, the input port being in an open state at least during the second predetermined duration.

Abstract: The cold plasma sterilization device for the sterilization of at least one object is placed in a container enclosing at least a gas or a gas mixture suitable for generating a cold plasma. The device includes a closed vessel in which a support for receiving the container is arranged. There is a device for subjecting the vessel to a secondary vacuum of the order of 10?3 to 10?7 millibar. There is an electron cyclotron resonance generator for generating, in the vessel, a flow of microwaves coupled to a magnetic field at least in a phase of initialization of the cold plasma. There is also a device for polarization of the support of the container.
