The Department of Defense, through the Naval Medical Research Center, is seeking a contractor to supply medical-grade compressed carbon dioxide (CO2) cylinders for research purposes at the Naval Medical Research Unit San Antonio (NAMRU-SA). The contract requires the vendor to provide six 50-pound CO2 cylinders with a CGA 320 connection, ensuring prompt delivery within two days of an order due to limited storage capacity, and includes rental fees for year-round on-site availability. This procurement is critical for supporting NAMRU-SA's cell culture experiments and maintaining research integrity, with the contract spanning a base period of 12 months and three optional 12-month extensions, totaling up to 48 months. Interested vendors can contact Timothy A. Daniels at timothy.a.daniels18.civ@health.mil or by phone at 301-319-6411 for further details.
