What you are buying
A refurbished and warrantied Agilent 1260 Infinity G1314B Variable Wavelength Detector (VWD) VL. It measures absorbance at selected wavelengths, built for standard HPLC data rates rather than the faster fast-HPLC rate of the VL+ variant.
Every unit we sell 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 designed the 1260 Infinity Variable Wavelength Detector VL to serve as a cost-effective, high-productivity optical sensor for everyday laboratory applications. Agilent highlights this module for its robust optical path, which utilizes a single Deuterium lamp and a dual-beam design to maintain low baseline noise and drift margins. Supporting standard data acquisition rates up to 55 Hz, the G1314B easily handles the peak widths generated by routine analytical HPLC methods. It stands as a low-maintenance, dependable workhorse featuring electronic flow cell identification, an integrated runtime log, and built-in diagnostic tools optimized to deliver consistent compliance and stable performance for budget-conscious laboratories.
What each module does
Variable wavelength detection
Measures absorbance at selected wavelengths, over a range of roughly 190 to 600 nm, at data rates up to 13 Hz. It drops into a compatible 1260 Infinity HPLC stack under OpenLab CDS or ChemStation.
Rather than supporting ultra-high-speed spectral scanning, the Agilent G1314B operates as a dedicated, single-channel ultraviolet-visible (UV-Vis) optical detector within a High-Performance Liquid Chromatography (HPLC) stack. Positioned directly inline after the column compartment, its primary job is to measure the absorbance of eluting components at a single, user-selected wavelength. This process executes several critical system-wide functions:
- Routine Compound Quantitation: It focuses a targeted ultraviolet light path through the flow cell to measure sample concentrations with linear precision across a broad concentration range.
- Compensates for Ambient Fluctuations: It directs a portion of the source beam to a reference photodiode, actively compensating for lamp energy fluctuations to keep the baseline steady.
- Simplified Method Development: It allows the operator to dynamically change the target wavelength via time-programmed steps throughout a single run, optimizing response factors for different peaks.
- Automated Device Tracking: It interfaces with the rest of the 1200 or 1260 series stack to record lamp ignition cycles and flow cell runtime metrics, simplifying GLP routine auditing.

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.
