Filtration, Chromatography, ULTRA-WARE® Filtration/Delivery Caps, DWK Life Sciences

• Patent No. 5,397,467
• This cap combines the mobile phase filtration, sparging/degassing, storage and delivery functions
• All tubing connections are made in the back of the cap, reducing the typical clutter of tubing at the reservoirs
• An integral check valve in the sparge port prevents the mobile phase from backing up into the gas lines
• A pressure release valve prevents the reservoir from being accidentally over-pressurized
• The 1/4"-28 fitting connections allow easy connection to any HPLC pump system
• Cap body is manufactured from glass-filled PTFE
• Cap will fit any reservoir or bottle with a GL 45 thread
• Not THF Resistant

• Patent No. 5,397,467
• Specially designed to permit the recirculation of mobile phase back into the reservoir while maintaining the helium sparged environment.
• This cap also performs stepwise filtration, sparging/degassing, storage and delivery to the HPLC pump
• An integral check valve prevents mobile phase from backing up into the gas lines
• A pressure release valve protects the reservoir from being accidentally over-pressurized
• The 1/4”-28 fitting connections allow easy connection to any HPLC pump system
• Cap body is manufactured from glass-filled PTFE
