Citadel pleated membrane cartridges feature a PTFE membrane and PFA structural components to provide excellent chemical and temperature resistance for aggressive chemical applications such as etchers, strippers, cleaners and bulk chemicals.
The all- fluoropolymer construction provides for the highest level of fluid purity and will exhibit rapid rinse-up to 18 MΩ-cm resistivity and single digit ppb levels of TOC.
Citadel filter cartridges are produced and manufactured in an ISO cleanroom and are 100% integrity tested to ensure performance standards.
Manufactured, flushed, tested and packaged in an ISO Class 7 Cleanroom Environment
Filters are flushed with 18 MΩ-cm DI water to ensure low extractables and low particle shedding
100% integrity tested to provide reliable performance
Resistivity rinse-up to 18 MΩ-cm and single digit ppb TOC levels with minimal throughput
Pore size ratings of 0.05, 0.1 and 0.2 micron to meet a broad range of applications
Wet-Pack option available to eliminate the requirement for solvent pre-wetting in aqueous applications
