Agilent 1200 HPLC G1312B SL Binary Pump

The Agilent G1312B SL Binary Pump features a two-channel, dual-piston in-series design which comprises all essential functions of a solvent delivery system. Metering of solvent and delivery to the high-pressure side are performed by two pump assemblies which can generate pressure up to 400 bar. Each channel comprises a pump assembly including pump drive, pump head, active inlet valve, and outlet valve. Both channels are connected in a low-volume mixing chamber which is connected by a capillary coil to a damping unit and a mixer. The design of the 1200 G1312B SL with variable stroke volume allows pulse-free solvent delivery and efficient mixing. An inlet-valve electronically activated and synchronized to piston stroke-eliminates vapor formation with volatile solvents and is maintenance free.

All of our equipment will be fully tested to perform at factory specifications before being shipped.
The Agilent 1200 HPLC G1312B SL Binary Pump includes:
  • > Power Cord
  • > Operator's Guide
  • > Full 90 Day Parts and Labor Warranty
