What you are buying
An Agilent G4767A Supercritical Fluid Chromatography (SFC) Multisampler. Comes expertly refurbished, with warranty coverage.
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 engineered the 1260 Infinity II SFC Multisampler to provide a combination of scalability, sample container flexibility, and injection precision for supercritical fluid chromatography applications. Agilent highlights this module for its proprietary Feed Injection Technology, which draws sample volumes under atmospheric conditions, smoothly pressurizes them to match system pressure, and introduces them via an ultra-fast syringing process. This design completely avoids expansion of the supercritical fluid carrier gas, resulting in LC-like peak reproducibility. Incorporating a modular drawer layout and advanced Cartesian robotics, it can expand to manage thousands of samples while ensuring low carryover via its automated multi-wash routines.
What this module does
Pressurized sample injection & automated sequencing
Rather than acting as a standard vial deck, the Agilent G4767A serves as a sophisticated, high-pressure sample handling and injection robot within a Supercritical Fluid Chromatography (SFC) or hybrid LC system stack. Positioned along the pressurized flow path, its primary job is to safely automate the loading of samples into high-pressure streams without disrupting supercritical phase stability. This process executes several critical system-wide functions:
Preserves Carrier Integrity: It manages the fluid transitions seamlessly during sample loading, ensuring the CO2-based mobile phase stays above critical thresholds to prevent phase separation.
Ultra-High Sample Capacity: It coordinates a multi-tier drawer system using a precise X-Y-Z Cartesian drive to manage up to 16 shallow microplates or up to 6,144 unique samples simultaneously.
Eliminates Injection Dispersion: It operates an ultra-fast syringe mechanism that cuts conventional loading lag times, reducing extra-column peak dispersion during fast chromatographic runs.
Hybrid Operational Flex: It can switch between optimized analytical SFC and standard high-pressure HPLC modes, maximizing stack versatility for modern multi-method facilities.

What “GenTech Certified” means
Refurbishment at GenTech is a defined process, not a wipe-down. Every system moves through the same specific stages.
1. Disassembly and rebuild. Solution Scientists strip the instrument down, clean each module inside and out, and rebuild it from the frame up. They replace pump seals, pistons, and check valves to specification.
2. Configuration and new parts. Solution Scientists install the options and modules you selected and fit new wear parts throughout. They replace the detector lamp with a new one and reset the lamp hours.
3. Diagnostic and performance testing. Solution Scientists tune and calibrate the instrument, run system diagnostics, and confirm detector wavelength accuracy. They test full-system pressure and gradient performance against OEM and published benchmarks using known reference chemicals.
4. Delivery and installation. The instrument ships in protective packing with a one-year warranty option and professional installation available from a GenTech Solution Scientist.
Labs that run this system
The 1260 HPLC is method-compatible across the techniques most regulated and research labs run every day. These are the application areas buyers ask about most.
High-Throughput Enantiomer and Chiral Separations
Pharma discovery labs utilize the G4767A to run high-density chiral screening arrays using thousands of unique targets. Feed Injection technology ensures the precise volumetric deliveries required to separate and quantify trace enantiomeric impurities.
Automated Screening of Complex Soil Contaminants
Environmental testing networks deploy this multisampler to process high-volume extractions of non-polar persistent organic pollutants. Automated robotic handling manages extensive plate sequences without manual intervention, streamlining strict regulatory turnaround schedules.
Rapid Lipophilic Nutrient and Lipid Assays
Food safety facilities rely on the G4767A to automate large sample batches when profiling fat-soluble vitamins, oils, and nutritional lipids. Robust external needle wash routines eliminate matrix carryover, keeping high-pressure runs contamination-free.
High-Efficiency Potency and Terpene Fingerprinting
Large-scale cannabis testing centers use this high-capacity module to screen raw materials using carbon dioxide mobile phases. Large well-plate drawer accommodations maximize instrument uptime, generating reliable potency profiles around the clock.
Defensible Multi-Target Designer Drug Sequences
Crime laboratories apply this multisampler to rapidly clear extensive caseload backlogs involving complex isomeric designer drugs. Exceptional injection linearity creates highly reproducible retention matches, ensuring legally sound data for courtroom verification.
