Agilent 1200 Series G4225A Degasser

This Agilent 1200 Series G4225A Vacuum Degasser is a used HPLC solvent management module offered in tested, functional condition. Its job is to remove dissolved gases from mobile phase solvents before they reach the pump, which prevents bubble formation, baseline noise, and pump cavitation during analytical runs. This unit fits directly into 1200 series HPLC stacks and similarly configured Agilent systems already in service. Consistent degassing is a foundational requirement for stable, reproducible chromatography, and this G4225A module delivers that function reliably across multiple solvent channels, supporting both isocratic and gradient methods. Laboratories running routine quality control assays, method validation studies, or high sample throughput work benefit from the steady baseline and reduced pump maintenance that proper degassing provides. As used laboratory equipment, this degasser is sold functional and ready to install, and buyers should verify vacuum performance and check for any solvent line wear during setup. It is a practical, budget-friendly way to keep an existing Agilent 1200 series HPLC system running cleanly without paying for a new solvent management module.
