Abstract
A method for treating a flexible plastic substrate is provided herein. The method includes establishing an atmospheric pressure plasma beam from an inert gas using a power of greater than about 90W, directing the plasma beam toward a surface of the flexible polymer substrate, and scanning the plasma beam across the surface of the polymer substrate to form a treated substrate surface.
Claims20
A method for treating a flexible polymer substrate for use in a bioprocess system, the method comprising:
- establishing an atmospheric pressure plasma beam from helium using a power of greater than about 90 W in a plasma generator;
- directing the plasma beam from a plasma outlet of the plasma generator toward a surface of the flexible polymer substrate positioned on a substrate support, wherein a ground electrode is disposed in the substrate support;
- and
- scanning the plasma beam over at least a portion of the surface of the polymer substrate to form a treated substrate surface, wherein scanning the portion of the surface of the polymer substrate removes an extractable or leachable compound.
