Pre-wetting Hydrophobic Cartridges
Pre-wetting a hydrophobic PTFE filter cartridge (Citadel or TefTEC) is crucial for ensuring proper filtration, especially when filtering aqueous solutions.
Graver Technologies' Citadel and TefTECfilter cartridges utilize this essential pre-wetting procedure, typicallyemploying isopropanol (IPA) or IPA/deionized water solutions as wetting agents.The process involves either submersion methods or in-line flushing techniques,followed by thorough rinsing with purified water to remove residual wettingfluids.
Keybenefits of proper pre-wetting include improved filtration efficiency,consistent performance, and reliable integrity testing results. Criticalconsiderations include pore size compatibility, timing requirements, andimmediate installation after preparation to prevent membrane drying.
Forenhanced convenience, pre-wetted filter options are available, eliminatingon-site preparation and reducing exposure to organic solvents. Theseready-to-use filters arrive packaged in sterile ultra-high purity deionizedwater, streamlining installation processes while maintaining superiorfiltration performance standards.
