This opportunity is for a service contract covering two Zeiss Merlin SEM instruments and a Gatan 3View Serial Block-Face Device. The contractor must provide on-site support, as remote access is not permitted, and must adhere to a strict repair timeframe for the SEMs, though best efforts are acceptable for the Gatan device. Software and firmware updates are limited to the current licensed version series, with major upgrades excluded. The contract covers a base period only, with no option years, and the instruments are currently operational under an existing service agreement. The location for performance is not specified in the description.
