Filter Cartridges feature all-fluoropolymer design.

Graver Introduces Citadel All-Fluoropolymer Filter Cartridge

Graver Technologies, LLC announces the release of the Citadel(TM), all-fluoropolymer filter cartridge series. Citadel filter cartridges feature a PTFE membrane with PFA structural components to provide excellent chemical and temperature resistance for microelectronics applications. The applications include aggressive chemicals used in etching, stripping and cleaning processes as well as the filtration of bulk chemical delivery systems requiring the upmost cleanliness and compatibility.

Citadel all-fluoropolymer filter cartridge is specifically engineered for use in the most critical applications within the microelectronics market. 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. Since PTFE is a naturally hydrophobic media, a pre-wet version is also available when filtering aqueous based chemicals to reduce the concerns with on-site preparation.
