1290 Infinity II Preparative LC System

The 1290 Infinity II Preparative LC System is designed for the purification laboratory that needs increased daily throughput by offering automated sample injection and fraction collection, smooth control of LC valves, and flexible access to up to four analytical columns and six preparative columns.

Easily exchangeable pump heads enable delivery of flow rates of up to 200 mL/min, making the system ideally suited for both analytical scouting columns and preparative columns with internal diameters between 4.6 and 50 mm.
