NOAA intends to award a sole-source purchase order to McLane Research Laboratories for an Imaging Flow Cytobot system to support harmful algal bloom monitoring and forecasting. The justification is that McLane is the sole manufacturer and distributor of this specific equipment in the United States. Delivery is required within 12 months from the date of award. While this is a pre-solicitation notice for a non-competitive action, firms believing they can meet the requirements may submit substantiating documentation to the point of contact within 15 days of the notice's publication.
