To help protect your investment and further extend the life of our already-rugged LC columns, Restek offers the patent-pending guard column hardware developed by Optimize Technologies. A Restek LC guard cartridge in an EXP direct connect holder is the ultimate in column protection.
- Free-Turn architecture lets you change cartridges by hand without breaking inlet/outlet fluid connections—no tools needed
- Patented titanium hybrid ferrules can be installed repeatedly without compromising high-pressure seal
- Auto-adjusting design provides ZDV (zero dead volume) connection to any 10-32 female port
- EXP direct connect holder requires separate guard column cartridges; available from Restek in 2.1, 3.0, and 4.6 mm
- Pair with EXP hand-tight fitting (cat.# 25937–25939) for tool-free installation
Maximum holder pressure: 20,000 psi (1,400 bar)
