Agilent 1100 Series - G1312A HPLC Binary Pump, Agilent Technologies (CAT#: STEM-C-0033-LGZ)

The manufacturer of Agilent 1100 Series - G1312A HPLC Binary Pump is Agilent Technologies. Model is 1100 Series - G1312A. The binary pump can be controlled remotely by chemical station software or an external G1323 controller. The speed proportional valve and pre-configured vacuum degassed 1100 binary pump allow easy low-pressure mixing of up to four solvents with maximum flexibility in solvent selection.

Condition: used
Hydraulic system: Two dual piston in series pumps with proprietary servo-controlled variable stroke drive, floating piston design and active inlet valve
Setable flow range: Setpoints 0.001 - 5 ml/min, in 0.001 ml/min increments
Flow range 1 - 5.0 ml/min
Flow precision: < 0.3 % RSD (typically 0.15 %), based on retention time, at 1 ml/min
Pressure: Operating range 0 400 bar (0 - 5880 psi) up to 5 ml/min
Pressure pulsation: < 2 %amplitude (typically < 1 %), at 1 ml/min isopropanol, at all pressures > 1 MPa
Compressibility compensation: User-selectable, based on mobile phase compressibility
Recommended pH range: 0 - 12.5, solvents with pH < 2.3 should not contain acids which attack stainless steel
Gradient formation: High-pressure binary mixing, delay volume 180 - 480 μl without mixer, 600 - 900 μl with mixer, dependent on back pressure
Composition range 1- 99 % or 5 μl/min per channel, whatever is greater
Composition precision < 0.2 % SD, at 0.1 and 1 ml/min
Control and data evaluation Agilent ChemStation for LC Control and data evaluation

1. The Agilent 1100 G1312A is an optimized design that ensures almost no pulse and steady solvent flow with dual floating pistons.
2. This design with variable stroke volume allows pulseless solvent delivery and efficient mixing.
3. The intake valve and piston stroke synchronous electric start, eliminate the steam in volatile solvents, no maintenance.
4. High-speed proportional valves and pre-configured vacuum degassed 1100 binary pumps allow easy low-pressure mixing of up to four solvents with maximum flexibility in solvent selection.
5. Easy to use and durable.
6. The binary pump can be controlled remotely by chemical station software or an external G1323 controller.
