What you are buying
A refurbished Agilent 1200 Series G1365D multiple wavelength detector. It records absorbance at up to eight wavelengths at once for identification and quantitation in a single run.
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 detector
Agilent built the G1365D around a 1024-element photodiode array with deuterium and tungsten lamps, covering 190 to 950 nanometers. Data rate reaches up to 80 Hz across up to 8 simultaneous wavelengths. Short-term noise runs about 1 x 10-5 AU at 254 and 750 nanometers, with drift under 2 x 10-3 AU per hour at 254 nanometers. Linear absorbance extends to 2 AU. A built-in holmium oxide filter verifies wavelength accuracy to within 1 nanometer. Programmable wavelength switching selects a different wavelength automatically during a run. A temperature-controlled flow cell holds the signal steady against ambient temperature swings. Early Maintenance Feedback tracks lamp burn time against a user-set limit and keeps an electronic record of maintenance and errors. The detector communicates over CAN, GPIB, RS-232C, and APG Remote, with LAN available as an option.
What this module does
Multiple wavelength detection
As a standalone multiple wavelength detector, the Agilent G1365D acts as the optical evaluation hub of an HPLC stack.  The detector records absorbance at up to eight selected wavelengths at once, over a range of roughly 190 to 950 nm. It drops into a compatible 1200 HPLC stack under OpenLab CDS or ChemStation.
The MWD executes several precision analytical tasks:
• Simultaneous Multi-Signal Capture
• Dual-Lamp Spectrum Coverage
• Variable Slit Control
• Automatic Wavelength Verification
• Standard Flow Cell Containment

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
Because the Agilent 1200 MWD captures up to 8 discrete UV-Vis signals simultaneously, it is highly valued by laboratories that analyze multi-component mixtures where different molecules absorb light at entirely separate wavelengths. These are the application areas buyers ask about most.
Multi-Component Formulations and Cleaning Validation
The Agilent G1365D enables chemists to monitor multiple active ingredients, preservatives, and excipients at optimized wavelengths during a single chromatographic run. This simultaneous analysis supports accurate purity testing and cleaning validation while maximizing sample throughput.
High-Concentration Contaminant and Dye Profiling
Ideal for routine monitoring profiles tracking high-abundance point-source contaminants, industrial wash runoff, and agricultural components. The 1200 MWD’s expanded 190–950 nm range provides the multi-signal tracking needed to accurately quantify contrasting targets in a unified waste stream injection.
Multi-Target Vitamin and Additive Quantitation
Food safety and cannabis processing labs use the Agilent 1200 MWD to analyze additives, nutritional components, and active compounds. By monitoring multiple analytes at optimal wavelengths in a single run, laboratories can streamline quality control, reduce repeat testing, and improve throughput.
Illicit Substance Profiling and Seizure Analysis
The Agilent 1200 MWD enables simultaneous monitoring of multiple compounds in complex mixtures, including narcotics, adulterants, and manufacturing residues. Its multi-wavelength detection capabilities provide detailed chromatographic data to support accurate substance identification, reliable documentation, and forensic investigations.
