Agilent 1260 Infinity Quaternary Pump VL 400 bar (Refurbished)

Universal pump now with extended power range

The Agilent 1260 Infinity quaternary pump now comes with an extended pressure range up to 400 bar. This allows the use of columns with smaller particle sizes and results in higher resolution or faster separations. The design ensures a truly pulseless and stable solvent flow thanks to two pistons in series, which are precisely controlled by servo motors. Variable stroke volume allows pulse-free solvent delivery and efficient mixing. The Agilent 1260 Infinity quaternary pump provides the ultimate flexibility in automated solvent mixing and is recommended for a wide range of research, routine and method development applications.

Features

• Maximum pressure of 400 bar using smaller particle size columns for higher resolution and faster separations.
• This performance range allows the use of longer columns and/or more viscous solvents as an alternative to acetonitrile.
• The wide flow rate range of up to 10 ml/min perfectly supports standard to semi-preparative applications. Perfect choice for 4.6 and 3.0 mm diameter columns.
• Speeds up method development, mobile phase preparation and HPLC system flushing by offering convenient access to up to four solvents for isocratic or gradient analysis.
• Easy, fast and safe method transfer from HPLC to sub-2micron columns.
• New degasser technology integrated in the pump.
• Application focus: Routine environmental and food applications as well as method development in the pharmaceutical industry.
• Minimal maintenance and lower operating costs through the use of robust materials such as stainless steel, titanium, gold, ruby, sapphire, ceramic, PEEK and PTFE. Optional active seal washing option for mobile phase with high salt content - to prevent corrosion.
