- High collection efficiency
- Extremely low pressure drop
- Higher throughput capacity
- Black backing ensures proper orientation
Improves Data Collection
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.*
Choice of Pore Sizes
Fluoropore membranes are available in 3 and 5 µm pore sizes. The smaller pore size provides low FWHM. The larger pore size has very low pressure drop and greater throughput capacity, which minimizes the number of filter changeouts.
Contrasting Backing Material
The contrast between the top (white side) and bottom (black side) of the filter prevents incorrect installation in sampling devices.
*FWHM is defined as the full width at half of the maximum height of the P0-218 peak obtained during sampling of room air.
