Optimize Technologies EXPGuard Column Cartridge, 4.6mm x 5mm, Phenyl-Hexyl, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
