This is a used tested working Agilent 1290 Infinity II G7161B Preparative Binary Pump.
The Agilent 1290 Infinity II G7161B Prep Binary Pump features easily interchangeable pump heads and high-pressure mixing, delivering flow rates from 1 to 200 mL/min at pressures up to 600 bar. It allows for seamless scale-up across various applications, supporting column IDs from 4.6 to 50.0 mm. As the solvent delivery module of choice, it ensures high-quality HPLC separations for both analytical and preparative-scale purification workflows.
This upgraded version of the 1260 Infinity II Preparative Binary Pump offers maximum flexibility, ready to meet any purification challenge. Its built-in solvent selection valve allows switching between two different solvents per channel, expanding its application range. With an automated seal-wash and dual-piston rapid-refill design, it delivers exceptional chromatographic performance for everyday use.
Features:
- Easy-to-change pump heads provide dynamic flow range up to 200 mL/min at maximum 600 bar for versatile application within a wide range of preparative workflows
- High-pressure binary gradient formation allows operation without degasser
- Outstanding retention time stability and binary gradient compositional accuracy for routine and specialty operation provides reliable chromatographic performance for any separation challenge
- Second built-in pressure transducer allows movement of the purification gradient mixing point to any point within the system, allowing purification of highly nonpolar compounds
- Rapid switching between up to four solvents enhances the application range and saves time by omitting solvent line purging
- Upper and lower pressure limits with automatic cutoff increase safety in the event of column blockage or leakage
- Automated seal wash for extended piston seal lifetime
