Agilent 1260 Infinity II Preparative Binary Pump by Agilent Technologies

The 1260 Infinity II Preparative Binary Pump is an affordable high-pressure gradient pump for LC purification. The pump offers a dynamic flow rate range from 1 to 50 mL/min at up to 420 bar, allowing workflows on columns from 9.4 to 30 mm inner diameter. 

This versatile pump is engineered for continuous use and provides reliable and rugged performance through a dual-piston, rapid-refill design. It offers automated seal wash for increased seal lifetime plus outstanding retention time stability, and is ideally suited for daily operation within a broad range of semipreparative applications.

Features:

• Dynamic flow range up to 50 mL/min at maximum 420 bar allows versatile application within a wide range of semipreparative workflows
• High-pressure binary gradient formation allows operation without degasser
• Outstanding retention time stability and binary gradient compositional accuracy for routine operation and reliable chromatographic performance
• Upper and lower pressure limits with automatic cutoff for increased safety in the event of column blockage or leakage
• Automated seal wash for extended piston seal lifetime
