What you are buying
A refurbished Agilent 1200 Series G1310A isocratic pump. It delivers a single-solvent mobile phase to the column at constant, reproducible flow.
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 1200 Series Isocratic Pump as the dependable workhorse for laboratories dedicated to routine analytical tasks and quality control applications. Agilent highlights this module for its rugged dual-floating, series-connected piston design, which features automated stroke length adjustment to minimize pressure pulsations and deliver highly reproducible retention times. Built on a modular, space-saving benchtop footprint, it focuses strictly on long-term performance stability and exceptionally low maintenance costs. It serves as an accessible, highly robust fluidics solution for specialized applications that require a constant, single-solvent mobile phase concentration without the added complexity of gradient mixing.
What this module does
Isocratic pumping
Delivers a single-solvent mobile phase at constant flow. Stable flow is the basis for the retention-time reproducibility every quantitative method depends on.
As a standalone isocratic liquid chromatography pump, the Agilent G1310A manages the fundamental task of fluidic delivery under pressure, executing several essential mechanical operations:
Pulse-Free Solenoid Delivery: It utilizes a high-precision dual-piston mechanism with electronic stroke control to continuously deliver mobile phase solvents at high pressures with minimal baseline ripple.
Constant Flow Profile: It pumps a single, unvarying solvent or pre-mixed mobile phase blend throughout the entire chromatographic sequence, making it ideal for applications where compound separation does not require inline gradient shifting.
Active Seal Washing: It features a built-in rinse path that flushes the backsides of the pump pistons, physically preventing salt crystallization from buffer solutions to maximize the operational lifespan of the high-pressure seals.
Modular Front-End Integration: It communicates seamlessly via CAN or LAN connections to sync with injection modules and optical detectors under standard chromatography data systems, ensuring unified sequence control.

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 1200 HPLC is method-compatible across the techniques most regulated and research labs run every day. These are the application areas buyers ask about most.
Routine Quality Control and Identity Testing
In high-volume production facilities, QA/QC laboratories run dedicated, validated methods to confirm the identity, purity, and concentration of active raw materials and finished products. The Agilent 1200 Isocratic pump provides the stable, unvarying flow environment required for these routine assays, keeping maintenance costs low while satisfying strict regulatory manufacturing metrics.
High-Concentration Contaminant and Surfactant Screening
Isocratic flow systems monitor targeted chemical contaminants that do not require complex gradient steps. The 1200 Isocratic pump is ideal for  methods tracking high-abundance contaminants such as industrial dyes, standard phenols, and alkylbenzene sulfonate surfactants in wastewater streams.
Dedicated Sugar and Carbohydrate Profiling
The analysis of simple sugars (such as glucose, fructose, and sucrose) and organic acids in juices or honey is almost exclusively performed using isocratic refractive index (RI) or electrochemical detection. The G1310A is the ideal tool for these dedicated setups, ensuring the highly stable, pulse-free flow that noise-sensitive RI detectors require for accurate quantification.
High-Throughput Potency Profiling
For the rapid quantification of total THC, CBD, and minor cannabinoids to satisfy legal compliance and product labeling requirements. The Agilent G1310A provides the extreme flow precision and stable pressure environment needed to run these high-volume potency sequences efficiently.
High-Volume Endogenous Screening Panels
Many specialized clinical testing panels, such as analyzing hemoglobin variants (HbA1c) or routine vitamin profiling, utilize specialized, pre-mixed commercial kit buffers that run under isocratic conditions. The rugged mechanical design of the 1200 Isocratic pump delivers the round-the-clock reliability these high-capacity clinical lines require to maintain quick sample turnaround times.
Targeted Drug Control and Seizure Analysis
Labs analyzing seized illicit substances often process large batches of highly concentrated samples. An isocratic separation method provides a rapid, cost-effective screening approach for targeted confirmation of common bulk narcotics. The G1310A’s mechanical reliability and reproducible retention times ensure quick sample turnaround times while fulfilling legal chain-of-custody documentation requirements.
Size Exclusion & Gel Permeation Chromatography (SEC/GPC)
Characterizing polymer molecular weight distributions via GPC requires a single, continuous solvent flow (such as THF or THF/chloroform blends) to cleanly wash molecules through size-exclusion columns. The strict flow precision and baseline stability of the G1310A ensure highly accurate molecular weight tracking, making it a staple tool for materials science and university polymer laboratories.
