PTFE Membrane Cartridge
EPTFE Electronics Grade filter cartridges provide superior chemical resistance for high-purity microelectronics applications requiring contaminant removal to 0.02μ.The EPTFE Series offers consistent removal of contaminants from aggressive fluids and organic solvents. In air and gas applications, the single-layer PTFE membrane, delivers superior hydrophobicity to polypropylene or PVDF; offering the best option to prevent water retention, flow blockage and microbial growth. The extend-area option offers up to 40% more surface area. This additional area results in significant increases in flowrate and loading capacity in the same footprint.
| Feature |
| Excellent chemical compatibility. |
| Suitable for filtering organic solvents and acid bases. |
| Pleated design for increased surface area. |
| Low pressure loss and longer service life. |
| Retention rating down to 0.03 μm. |
| Graded pore density for higher dirt holding capacity. |
| Rigid polypropylene outer cage protects filter media. |
| Manufactured from materials which are listed for food contact applications in Title 21 of the U.S. Code of Federal Regulations. |
| Cartridges are free of binders, resins, and adhesives. |
| All polypropylene components meet the specifications for biological safety per USP Class VI – 121 ̊C for plastics. |
| Cartridges are available with wet-pack option (60/40 IPA/DI water solution) to eliminate the need to wet-out in the environment. |
