Using preparative guards is a proven and cost effective way to extend the lifetime of your preparative columns. Thermo Scientific™ Preparative Guard Column Holders allow for easy assembly and connection of the guard column to the preparative column.
Selecting the appropriate preparative guard holder for your size of preparative HPLC column is important. We offer a range of guard holder sizes which are all in a convenient stand-alone format that requires connections from the LC inlet and outlet to the preparative LC column.
Our preparative guard holders are available in 1/16 in. or 1/8 in. connection fittings in the larger guard sizes to be compatible with your Preparative HPLC system hardware.
