The National Institute on Biomedical Imaging and Bioengineering requires a service contract for a specialized Zeiss SIGMA-VP scanning electron microscope with 3View capabilities, used for 3D imaging of cellular structures. The contract is essential because only experienced Zeiss engineers can service this equipment, provide parts, or offer remote assistance. The instrument is located in NIBIB’s BEPS Shared Resource at the NIH and is used by researchers across multiple NIH institutes. No specific budget amounts or submission timelines are mentioned in the description. The contract ensures the instrument remains at peak performance for critical research on tissues such as pancreatic islets, retina, cochlea, and blood platelets.
