The 1260 Infinity III Binary Pump is ideally suited for a broad range of UHPLC applications using columns with conventional, superficially porous or sub-2-micron particles. This pump delivers reproducible gradients for routine HPLC or UHPLC applications with UV or MS detection where speed, resolution, and uncompromised data quality are essential.
Features
- Configurable delay volume from standard down to 120 µL with flow range up to 5 mL/min for universal applicability
- Narrow-bore flow rates even at low percentages of organic solvent delivers high gradient performance for LC/MS applications
- 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
- Integrated high-efficiency degasser with low internal volume based on PTFE AF technology offers fast change-over of solvents for purging and priming
- Optional seal wash for high-salt mobile phases keeps maintenance to a minimum and reduces operating costs
- Optional solvent selection valve lets you choose two out of four solvents for higher method flexibility and more unattended operation
