Agilent 1260 Series - G1310B HPLC Isocratic Pump

Agilent 1260 Series - G1310B HPLC Isocratic Pump

Cambridge ID #: 17964

The Agilent Technologies 1200 Series (G1310B) 1260 Infinity Isocratic Pump is a HPLC workhorse for demanding QA/QC and routine applications, designed to provide virtually pulse-free and stable solvent flow. This delivery principle allows variable stroke volume optimized to selected flow rate. The broadened pressure range with maximum pressure of 600 bar allows the use of small particle size columns, longer columns, or alternative solvents of higher viscosity. Additionally, the G1310B is the ideal pump for GPC/SEC applications where run-to-run and day-to-day precision of retention times are important.



  • Settable flow range: set points 0.001 - 5 mL/min, in 0.001 mL/min increments
  • Flow range: 0.2 to 10.0 mL/min
  • Flow precision: ≤ 0.07 % RSD or ≤ 0.02 min SD
  • Flow accuracy: ± 1 % or 10 μL/min whatever is greater, pumping degassed H2O at 10 MPa (100 bar)
  • Pressure operating range:
    • Operating range up to 60 MPa (600 bar, 8700 psi) up to 5 mL/min
    • Operating range up to 20 MPa (200 bar, 2950 psi) up to 10 mL/min

Agilent 1100 Series - G1310A HPLC Isocratic Pump

Agilent 1100 Series - G1310A HPLC Isocratic Pump

Cambridge ID #: 14776

The HP / Agilent 1100 HPLC series is the current model and arguably the best design in the industry because of the optimized design of the quaternary pump ensuring 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. An inlet-valve electronically activated and synchronized to piston stroke - eliminates vapor formation with volatile solvents and is maintenance free. With high-speed proportioning valve and pre-configured vacuum degasser, for convenient low-pressure mixing of up to four solvents and highest flexibility in solvent choices.



  • Ease-of-use - handheld control module lets you enter operating parameters fast, store methods easily and display pressure profile, diagnostics and task-oriented information.
  • Durable - stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE ensure long lifetime. Seal wash option for high salt mobile phases keeps maintenance to a minimum for lower operation costs.
  • Wide flow range - up to 10 ml/min for broad HPLC work, including semi-preparative separations.
  • Better for GLP - built-in leak and pressure test with graphical presentation of pressure profiles, and early maintenance feedback.



  • Hydraulic system: Dual piston in series pump with proprietary servo-controlled variable stroke drive, floating pistons and active inlet valve
  • Settable flow range: .001– 10 ml/min, in 0.001 ml/min increments
  • Flow range: 2 – 10.0 ml/min
  • Recommended pH range: – 12.5, solvents with pH > 2.3 should not contain acids which attack stainless steel.
  • Operating voltage: 230V
