Atmospheric pressure non-thermal plasma device to clean and sterilize the surfaces of probes, cannulas, pin tools, pipettes and spray heads

摘要

The present invention relates to methods and apparatus for the use of atmospheric pressure non-thermal plasma to clean and sterilize the surfaces of liquid handling devices. In one embodiment, a method of cleaning a fluid handling device includes the steps of inserting a tip of the fluid handling device into an interior of a channel through a first opening disposed at a first end of the channel, wherein a first electrode is disposed adjacent an exterior of the channel; causing a plasma to be formed within the interior of the channel; and removing the fluid handling device from the channel through the first opening.
