The Agilent 1290 Infinity II Prep Binary Pump (G7161B) features easy-to-change pump heads and high-pressure mixing, delivering flow rates from 1 to 200 mL/min at up to 600 bar. Seamless scale-up across a broad range of applications is possible with column ids from 4.6 to 50.0 mm. The pump is the solvent delivery module of choice for achieving high-quality HPLC separations in analytical and preparative-scale purification workflows.
