Varian 3900 Gas Chromatography

Agilent 7890A GC System This system was removed from a university lab where it was surplus to requir (more)ements. The system is in fair cosmetic condition, with a few marks and scratches. It powers on, but no further testing has been conducted due to the absence of a PC and software. According to the previous owner, there are no known faults, but the system has been out of use for a few years and would likely need recommissioning. Specifications: - Serial No.: CN10809012 - Model: G3440A
