Please contact Pall Corporation to verify that the product conforms to your national legislation and/or regional regulatory requirements for water and food contact use.Rinse-up
Rinse-up to 18 Megohm-cm with a minimum of throughput.Autoclaving
Single-open-end Nexis T series filter cartridges can be autoclaved for 30 minutes at 121 °C (250 °F) under no end load conditions. However , filter cartridges should be allowed to cool to normal system operating temperatures prior to use.Steam sterilization

1 >90% retention rating by ASTM F-795 test. Nexis T series filter cartridge retention ratings are based on Pall's Dynamic Efficiency test protocol. This single pass, destructive challenge test is based on ASTM F-795 test procedures for determining the performance of a filter medium. Fine test dust is used as the test contaminant for filters in the 0.5 to 20 micron range. Coarse test dust is used for micron ratings above 20 micron. Additional information can be obtained by contacting Pall Corporation.
2 Provided that the maximum differential pressure is not exceeded based on temperature limits defined above.
3 Due to the very low flow resistance of the media in the more open grades, pressure drop is primarily related to turbulent loss through the center core. Flow rate is for a 25.4 cm (10 in.) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
