The G4800 laboratory-sized hydrogen generator is designed for multiple GC, FID and carrier gas applications. Also known as the "lab server," the G4800 is the only generator large enough to handle all carrier gas requirements. It utilizes Proton Exchange Membrane (PEM) cell stack and PSA technology to produce UHP hydrogen for laboratory applications.

Take your lab to the next level.
