Filtration, Chromatography, ULTRA-WARE® Filtration/Delivery Caps, DWK Life Sciences
ULTRA-WARE® 4-valve Filtration Cap (F301-1)
- 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
ULTRA-WARE® 5-valve Filtration Cap (F301-2)
- 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
- Cap will fit any reservoir or bottle with a GL 45 thread
