Lowest volume capillary connections. Two dual-piston, in-series pumps in one housing for a minimum of bench space and lowest internal and external volume. Only 180 – 480 µl internal volume (without mixer).
Low flow. Starting at typically 50 µl/min for reproducible gradients at low flow with solvent degassing.
Reliable design. With electronically-controlled active inlet-valves for flow rates up to 5.0 ml/min, the pump is also ideally suited to standard-bore chromatography. Floating pistons with path-of-least-resistance principle ensures highest seal lifetime.
Flow Precision: <0.3 % RSD (typically <0.15 % RSD)
Flow Range: Setpoints from 0.001 to 5.0 ml/min, in 0.001 ml/min increments
Operating range: 0 – 40 MPa (0 – 400 bar, 0 – 5880 psi)
Pulsation: <2 % amplitude (typically <1 %) at 1 ml/min isopropanol at all pressures >1 MPa (> 10 bar, >147 psi)
Compressibility compensation: User selectable, based on mobile phase compressibility
Delay volume: 180 – 480 µl (600-900 µl with mixer) dependent on back pressure
Recommended pH range: 1.0 – 12.5. Solvents with pH <2.3 should not contain acids which attack steel
GLP Features: Electronic records of maintenance and errors. Early maintenance feedback (EMF) continuously tracks instrument usage and displays feedback messages if preset limits are exceeded.

How GenTech Refurbishes Used Lab Instruments
Every refurbished instrument we sell undergoes a complete inspection of all electronics and performance review. The instruments undergo in-depth preventative maintenance procedures that include extensive cleaning, detector maintenance, line and pump flushing. Routine maintenance is also addressed and filters, liners, tubing, etc. are all replaced as needed. A full calibration and data verification is performed ensuring our used Gas Chromatography are returned to excellent working condition.
Our expert service engineers and chemists can install and custom configure the system to be compliant with the Methods you plan to run.
