In Particles on Surfaces – Part 1, witness wafer and settling plate data showed that particles and bacteria (i.e. viable particles) will settle on cleanroom surfaces. From this we can infer that particles do NOT behave as hard microscopic billiard balls, striking surfaces and rebounding into the air. Rather, through inelastic collisions with the surface, they [Read More…]
DOWNLOAD POSTER: An updated guide to properly folding and utilizing a low-linting wiper for maximum cleaning efficiency in a cleanroom, controlled or critical environment.
