NIST is seeking information from potential suppliers of a sub-boiling distillation system to purify ultrapure water to an extreme grade (UPW0) for developing semiconductor test materials and standards. The required system must not need a fume hood, have PTFE or PFA wetted components, and include automatic filling and draining with safety protections. The performance location is not specified, and the description does not include budget amounts or non-bid timelines. This is a market research request to inform a potential future procurement, not a commitment to award a contract.
