Restek HPLC and UHPLC Guard Holder Hardware – Reliable LC Column Protection

Restek HPLC and UHPLC Guard Holder Hardware and Accessories provide effective protection for analytical LC columns against particulates, strongly retained contaminants, and complex sample matrices. By selecting a guard cartridge with a stationary phase that matches the analytical column, column lifetime can be extended while maintaining chromatographic selectivity, efficiency, and reproducibility.

Restek EXP Guard Cartridges are designed for Raptor and Force LC columns and are available for HPLC and UHPLC applications. The EXP direct-connect holder supports pressures up to 20,000 psi (over 1,400 bar).

Restek Trident LC Column Protection Systems are designed for traditional HPLC columns, including Restek Ultra, Pinnacle DB, Pinnacle II, and Allure columns. The Trident holders offer three levels of protection (filter only, guard cartridge only, or a combination of filter and cartridge) and are available as Direct-connect or in-line holders to provide additional installation flexibility.

Restek Roc Guard Holder provide an economical guard solution specifically designed for Restek Roc HPLC columns.
