Agilent 1260 Infinity II HPLC System ONLY $39,999

What you are buying

Most pharmaceutical QC, environmental, and food-safety methods call for the separations the Agilent 1260 Infinity II runs. The quaternary pump blends up to four solvents at pressures to 600 bar; the vialsampler handles routine and high-throughput sequences; the thermostat holds column temperature steady; the diode array detector covers the full UV-visible range. GenTech assembles, plumbs, and tests this stack as one system. You receive an instrument that runs out of the crate rather than a set of modules to integrate.

Every unit moves through the GenTech Certified process. Solution Scientists disassemble and inspect each module, replace all consumables and degraded wear components, then tune and calibrate the instrument and verify performance against OEM and published benchmarks using known reference chemicals. The instrument ships with its verification report. A certified-refurbished system gives you that performance without the capital cost or the lead time of a new purchase.

What Agilent says about this platform

Agilent positions the 1260 Infinity II as the successor to the 1100 and 1200 series and calls it the standard system for routine HPLC analysis. Agilent rates the platform for a ten-year service life. That lineage is the reason to buy one refurbished. The installed base is large, methods written on a 1100 or 1200 carry directly onto a 1260, and parts and trained service are everywhere. You inherit a mature, well-supported platform without paying new-instrument prices.

Quaternary or binary pump

The quaternary configuration suits the majority of isocratic and routine gradient work and gives you four-solvent blending flexibility. The binary configuration serves gradient-critical and high-pressure methods where pump precision matters most.

What each module does

Quaternary pump (G7111B). Delivers up to 600 bar across a flow range to 10 mL/min and blends as many as four solvents in a single method. The pressure range lets you run smaller-particle and longer columns for higher resolution and faster separations.

Vialsampler (G7129A). Holds up to 132 vials and injects 0.1 to 100 µL per run. A dedicated needle-flush port rinses the outside of the needle between injections, which keeps carryover low across long sequences.

Multicolumn thermostat (G7116A). Holds up to four columns at a steady temperature from below ambient to 85 °C and reaches each one directly through a Quick-Change switching valve under software control. You can run column selection or alternating regeneration without replumbing.

Diode array detector (G7115A). Reads from 190 to 950 nm, the full UV-visible range plus the near-infrared, which lets you quantify, confirm peak identity, and check peak purity in one run. Deuterium and tungsten lamps hold the baseline steady for clean integration.
