Agilent 1260 Infinity II Quaternary Pump by Agilent Technologies

The 1260 Infinity II Quaternary Pump is a gradient pump that uses low-pressure mixing for UHPLC gradient formation and solvent blending from up to four solvents. This pump operates at pressures up to 600 bar and flow rates up to 10 mL/min. 

The 1260 Infinity II Quaternary Pump combines proven reliability with highest flexibility in automated gradient formation and solvent blending, and is recommended for a wide range of research and routine applications as well as for method development.

Features:

• Wide flow range up to 10 mL/min supports standard analytical and semipreparative applications and is ideal for 4.6 and 3.0 mm id columns
• 600 bar maximum pressure allows you to use smaller particle size columns, longer columns, and/or higher viscous solvents as an alternative to acetonitrile for higher resolution and/or faster separations
• Convenient access to up to four solvents for isocratic or gradient analysis, accelerating method development, preparation of mobile phases, and system flushing
• Easy, fast, and secure transfer of methods from conventional columns to sub-2-micron columns
• Integrated high-efficiency degasser with low internal volume based on PTFE AF technology offers fast change-over of solvents for purging and priming
• Robust materials (stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK, and PTFE) withstand the most demanding applications, increasing pump longevity while reducing operating costs
• Optional seal wash for high-salt mobile phases keeps maintenance to a minimum and reduces operating costs
