NOAA intends to award a sole-source purchase order to Yokogawa Fluid Imaging Technologies for a FlowCam 8000 microscope, as they are the sole manufacturer and distributor in North America. The instrument is required for rapid, automated imaging and quantification of particles, primarily for plankton research and water quality monitoring. Delivery is required within 90 days from the date of award. The performance location is not specified, and no budget information is provided. While this is a pre-solicitation notice and not a request for competitive proposals, firms believing they can meet the requirements may submit substantiating documentation in writing within 15 days of the notice's publication.
