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

Apparatus for plasma cleaning, comprising:

• a plate having a conductive surface and an opposing dielectric surface, the plate having a plurality of openings extending through the conductive and dielectric surfaces;
• a plurality of hollow dielectric members coupled at a first end to the dielectric surface of the plate and extending in a direction opposite the conductive surface, each of the plurality of hollow dielectric members having a first opening at the first end aligned with a respective one of the plurality of openings in the plate;
• and
• an electrode coupled to a central portion of an outer surface of each of the hollow dielectric members.
