Particle Finder enumerates and measures foreign particles raning from 13 - 5000µm on filter membranes. The PF offers 10 channels of simultaneous particle counting, displays particle size and shape information, and provides particle count data in compliance with 21 CFR Part 11. PF, like the SPE CSS, also uses fully automated image acquistion and anaysis/documentation units to provide reproducable results regarding particle contamination in minutes.
