This is a notice of intent for a non-competitive, brand-name firm-fixed-price purchase order to Hamilton Company for a one-year OEM PREMIUM PLUS service contract covering a Hamilton Microlab VANTAGE liquid handling instrument. The service will be performed at the NIAID Vaccine Research Center. Hamilton is the original equipment manufacturer and the only responsible source for OEM-level preventive maintenance, calibration, diagnostics, and genuine replacement parts. The requirement is not set aside for small business and falls under the simplified acquisition threshold.
