Agilent 1100 HPLC G1312A Binary Pump

The Agilent 1100 G1312A Binary Pump ensures virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. This design with variable stroke volume allows pulse-free solvent delivery and efficient mixing. The G1312A’s inlet-valve is electronically activated and synchronized to piston stroke to eliminate vapor formation with volatile solvents and requires no maintenance. The high-speed proportioning valve and preconfigured vacuum degasser of the 1100 Binary Pump allows convenient low-pressure mixing of up to four solvents and the highest flexibility in solvent choices. This binary pump can be remotely controlled via chemstation software or by an external G1323 controller. The Agilent G1312A is easy to use, durable, and offers a wide flow range.

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

The Agilent 1100 HPLC G1312A Binary Pump includes:
  • > Firmware version A.06.54 (Can be changed upon request)
  • > Lab Advisor Diagnostic Report
  • > Lan Cable / Power Cord
  • > Operator's Manual
  • > Full 90 Day Parts and Labor Warranty
