The Department of Defense, through the Naval Medical Research Center (NMRC), intends to award a sole-source contract for the urgent repair of a Werfen GEM4000 blood gas analyzer, which has experienced a CoOx hardware failure (error 264). This repair is critical as it has halted operations related to Animal Protocol 0226 at the Environmental Health Effects Laboratory in Dayton, Ohio, and can only be performed by the manufacturer, Werfen USA, due to the proprietary nature of the technology. The NMRC has confirmed that Werfen USA is the sole supplier capable of addressing this urgent need, and the contract will be awarded under FAR Part 12 for commercial items. Interested vendors must be registered in the Systems for Award Management (SAM) and can contact Deborah Sharpe at deborah.m.sharpe2.civ@health.mil or Michael Ponczeck at michael.ponczek@us.af.mil for further information.
