Agilent 1290 Infinity Series G4220A Binary Pump

Product Information

As we delve into the mesmerizing world of laboratory equipment, we come across the remarkable Agilent 1290 Infinity Series G4220A Binary Pump. This incredible instrument, tested for basic power function, exhibits slight wear from normal use. The pump, comprising two identical pumps integrated into one housing, creates binary gradients by high-pressure mixing. It is also equipped with a degassing unit, enabling the best flow stability for maximum detector sensitivity. With applications ranging from high throughput methods to fast gradients on high-resolution columns, this pump delivers flow in the range of 0.05-5 mL/min against up to 1200 bar. The hydraulic system features dual pistons and servo-controlled variable stroke design, offering exceptional flow precision. Additionally, the pump operates with a compressibility compensation for automatic gradient formation and includes extensive diagnostics and safety features.
