333 HPLC Pump with H3 Pump Head Primary Solvent

The 333/334 Pumps are the optimal choice for preparative HPLC applications, offering multi-solvent selection and dynamic mixer for optimized gradient performance.

Overview × The 333/334 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. 333/334 Pumps—The Pumping Choice for Preparative HPLC The 333/334 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. For isocratic methods, choose the 333 master pump; choose the combination of the 333 and 334 Pumps for binary methods. Control 333/334 Pumps and an entire preparative HPLC system via TRILUTION® LC software. With the 333 Pump as master pump, control: • Flow-rate gradient • Four-solvent selection and step gradient (additional valve) • Composition gradient (one or two additional pumps) • Sample-injection pump • UV/VIS detector
