Raptor™ EXP® Guard Column Cartridges • 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. • Guard column cartridges require EXP® direct connect holder (cat.# 25808). • Pair with EXP® hand-tight fitting (cat.# 25937–25939) for tool-free installation. 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.
