The 334 Pumps are the ideal choice for preparative HPLC applications in normal and reverse-phase modes. All pumps offer multi-solvent selection, with an optional four-solvent valve that allows up to eight solvents. The pumps feature a variable-volume, dynamic mixer for optimized gradient performance. The 334 Pumps provide a preparative pumping solution to accommodate columns ranging from 10 mm to 50 mm ID in high pressure normal and reverse phases at flow rate from 1 mL/min to 200 mL/min and pressures up to 3040 psi (210 bar). Use milligram to gram injection levels—up to 15 g depending on column size and loading capacity. With additional pumps in parallel, you can double the flow rate up to 400 mL/min. Control 334 Pumps and an entire preparative HPLC system via TRILUTION® LC software.
