The NHLBI intends to award a sole source contract to Hamilton Company for a service agreement on a specific Hamilton STAR V liquid handler. The required services include preventive maintenance, repairs, technical support, and software updates. The work will support the instrument located at the NIH Clinical Center. The justification for a sole source award is that the manufacturer is the only authorized provider for this proprietary system. While not a request for competitive quotes, interested parties may submit capability statements for government consideration.
