The National Institutes of Health (NIH) intends to award a sole source, firm-fixed-price purchase order to Carl Zeiss Microscopy for a LSM 990 w/Airyscan-2 Microscope. This system is required for high-resolution imaging of mouse inner ear tissues and live zebrafish studies, offering superior resolution and reduced phototoxicity compared to the current LSM780. The microscope is a brand-name proprietary technology essential for ongoing research projects at the NIDCD. Performance of delivery, installation, and calibration will occur at the NIH facility in Bethesda, Maryland (9000 Rockville Pike, Building 35A, Room 1D-9333). No budget amount or non-bid timeline was specified in the description.
