Unlike fibrous filter media that trap particles in their matrix, Fluoropore (hydrophobic PTFE) membranes collect particles on their surface. This surface collection provides better detection efficiencies and lower FWHM measurements. Fluoropore membranes are available in 5 �m pore sizes. The pore size has very low pressure drop and greater throughput capacity, which minimizes the number of filter changeouts. The contrast between the top (white side) and bottom (black side) of the filter prevents incorrect installation in sampling devices. Fluoropore trade. Applications: Particle Monitoring.
