Foamtec PolyCHECK Swabs: The Ultimate Solution for Particle Contamination Analysis

Do you need to verify the cleanliness of your critical surfaces and identify the sources of particle contamination in your wafer fabs, medical device, pharmaceutical, or optics facilities?

If so, you need Foamtec PolyCHECK Swabs – the innovative inspection and detection swabs that enable fast and accurate sampling and analysis of foreign particles in ISO 1-8 cleanrooms.

Foamtec PolyCHECK Swabs are specially designed with a highly charged fabric that attracts and holds particle contamination on the swab surface. The fabric is white on one side and black on the other, allowing you to easily see the collected particles and transfer them to SEM stubs for further analysis.

Foamtec PolyCHECK Swabs are ideal for use with Scanning Electron Microscopy (SEM), X-ray Dispersion (EDX), and Fourier Transfer Infrared Spectroscopy (FTIR) techniques, which can help you perform risk assessments, close CAPAs, reduce scrap and rework, and eliminate contamination sources.

Foamtec PolyCHECK Swabs are autoclave safe, and can be used to sample hard-to-reach surfaces, such as workstations, process equipment, vacuum chambers, robotics, tooling, and devices.

Don’t let particle contamination compromise your product quality and performance. Order your Foamtec PolyCHECK Swabs today and get the best tool for cleaning validation and failure analysis.
