Agilent 1260 Infinity II HPLC GPC/SEC System with Refractive Index Detector (RID), and Isocratic Pump

Insights by AMPTIUS | AMP Tech Instruments

Accurate Polymer and Biomolecule Characterization

If your laboratory is struggling with baseline drift or inconsistent retention times during polymer and macromolecular weight determination, the Agilent 1260 Infinity II GPC/SEC system delivers the rock-solid isocratic flow and thermal stability your assays demand. Driven by a high-precision isocratic pump operating at pressures up to 600 bar (8,700 psi), this specialized size exclusion chromatography platform ensures pulse-free, highly reproducible solvent delivery for flawless molecular weight distribution modeling. The integrated Refractive Index Detector (RID) features advanced internal temperature control over both its optics and flow cell, substantially minimizing the thermal drift common when analyzing non-UV-absorbing compounds like polymers, proteins, and polysaccharides. It is an industry-standard, robust workhorse perfectly optimized for industrial chemical facilities conducting routine polymer quality control, pharmaceutical labs analyzing complex excipients, and biotechnology operations tracking biopolymers.

Agilent 1260 Infinity II HPLC GPC/SEC System with RID Detector and IsoPump: Refurbished System Benefits and Pricing

The Agilent 1260 Infinity II HPLC GPC/SEC System with a Refractive Index Detector (RID) and Isocratic Pump provides a powerful and cost-effective solution for polymer characterization, molecular weight determination, biopolymer analysis, and quality control applications. Certified refurbished systems typically range from approximately $28,000 to $45,000, offering significant savings compared to new systems, which commonly range from approximately $60,000 to $85,000 depending on configuration, software, and detector options. Beyond the initial acquisition cost, laboratories should budget for ongoing operational expenses including GPC/SEC columns, calibration standards, mobile phase solvents, pump seals, check valves, autosampler consumables, RID maintenance, software support, preventive maintenance, and compliance-related qualification services. Long-term ownership considerations may also include column replacement, flow path maintenance, detector servicing, and periodic performance verification to ensure consistent molecular weight accuracy and chromatographic reproducibility. Purchasing a certified refurbished Agilent 1260 Infinity II HPLC GPC/SEC System with RID and IsoPump allows laboratories to substantially reduce capital expenditures while maintaining access to precise molecular weight distribution analysis, reliable polymer characterization, robust isocratic performance, and proven Agilent reliability for applications in polymer manufacturing, materials science, biotechnology, chemical research, and industrial quality control.
