The Pathology and Laboratory Medicine Services department requires full-service support for its RO/DI water purification systems, including maintenance, corrective actions, parts, supplies, and technical support. The systems are point-of-use units designed to supply a few liters of pure water per day for laboratory applications. It is imperative that these systems operate at precise levels of efficiency, particularly for applications sensitive to bacteria and chemical contaminants. No specific timelines, budget, or location for performance are detailed in this description.
