About this file
This is a Draft Purchase Description for Standard Gas Mixtures and Cylinders for the Naval Surface Warfare Center (NSWC), Corona Division. The document outlines requirements for acquiring seven specialty gas mixtures with specific molecular compositions, including hydrogen, oxygen, helium, and nitrogen, with a blend pre-tolerance of ± 2%. The contract also calls for 28 high-pressure aluminum cylinders meeting Department of Transport (DOT) Specifications 3AL-2216, with an internal volume of 0.208 ft³, water capacity of 12.98 lb, and pressure capacity of approximately 30 cubic feet when filled to 2000 psig.
The gas mixtures are intended to support Navy Calibration Labs' calibration standard test equipment. Vendors must provide a certificate of analysis for each gas mixture, stating certified concentration and analytical uncertainty, with nitrogen balance components exempt from analysis. The cylinders must be labeled to indicate their contents. This pre-solicitation seeks potential sources capable of providing these specialized gas mixtures and cylinders, with interested parties invited to submit a capability statement including company details, business size, estimated unit pricing, lead times, and commentary on the draft purchase description.
