The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 47 units of an oxygen analyzer for repair or modification purposes. The procurement is based on National Stock Number (NSN) 7H-6630-015327090, and the government has determined that it is uneconomical to purchase the data or rights necessary for competitive sourcing, thus intending to negotiate with only one source under FAR 6.302-1. This equipment is critical for chemical analysis applications within military operations, and the government is not utilizing FAR Part 12 for this solicitation. Interested parties are encouraged to express their interest and capability to meet the requirement within 15 days of this notice, with proposals being accepted for 45 days from the publication date. For further inquiries, interested vendors can contact Madison Gray at (717) 605-4056 or via email at MADISON.M.GRAY4.CIV@US.NAVY.MIL.
