- Free-Turn architecture allows for cartridge changes by hand without disrupting the inlet and outlet fluid connections—no tools required.
- Patented titanium hybrid ferrules can be installed multiple times without affecting the high-pressure seal.
- Auto-adjusting design ensures a zero dead volume (ZDV) connection to any 10-32 female port.
- Guard column cartridges need the EXP direct connect holder (cat.# 25808).
- Combine with the EXP hand-tight fitting (cat.# 25937–25938) for installation without tools.
- This setup works excellently with any Raptor column to provide maximum protection against particulates and matrix contamination, particularly when employing dilute-and-shoot or other minimal sample preparation methods.
