The NIH Clinical Center’s Department of Transfusion Medicine/Center for Cellular Engineering intends to procure continued bulk liquid nitrogen delivery and tank rental services from Roberts Oxygen Company, Inc. for its 3T cell-manufacturing facility in Building 10, with the existing bulk tank located near the Building 10 Morgue. The anticipated period of performance is 10/16/2026 through 09/30/2027. The sole-source basis is that Roberts Oxygen owns and provides the installed tank, supplies the liquid nitrogen, and is the approved supplier; changing suppliers would require removal, new installation, requalification, added costs, and potential disruption to regulated cell manufacturing and clinical trials. Although this is not a request for competitive quotations or proposals, responsible sources may submit a capability statement demonstrating their ability to provide the required liquid nitrogen delivery and tank rental services in support of CCE operations.
