The Department of Defense, through the Naval Research Laboratory, intends to award a sole source purchase order for a laboratory water system that provides ASTM Type 1 water, characterized by a resistivity of greater than 18 MΩ-cm. The required system must operate from a domestic water source, have a small footprint to minimize laboratory space requirements, and allow for straightforward user-serviceable maintenance with reasonably consumable materials. This procurement is critical for laboratory operations, ensuring high-quality water for various research applications.
