Agilent 1260 Infinity HPLC G1312B Binary Pump

The Agilent 1260 Infinity HPLC G1312B Binary Pump is based on a two-channel, dual-piston in-series design which comprises all essential functions that a solvent delivery system has to fulfill. Metering of solvent and delivery to the high-pressure side are performed by two pump assemblies which can generate pressure up to 600 bar.

Each channel comprises a pump assembly including pump drive, pump head, active inlet valve with replaceable cartridge, and outlet valve. The two channels are fed into a low-volume mixing chamber which is connected via a restriction capillary coil to a damping unit and a mixer. A pressure sensor monitors the pump pressure. A purge valve with integrated PTFE frit is fitted to the pump outlet for convenient priming of the pumping system. Typical applications are high throughput methods with fast gradients on high resolution 2.1 mm columns. The pump is capable of delivering flow in the range of 0.1 to 5 mL/min.

All of our equipment is fully tested to perform at factory specifications before being shipped.

The Agilent 1260 Infinity HPLC G1312B Binary Pump includes:
  • > Firmware Version 06.50 (Can be changed upon request)
  • > Leak and Pressure Diagnostic Report
  • > Lan Cable / Power Cord
  • > Operator's Manual
  • > Full 90 Day Parts and Labor Warranty
