The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is seeking potential suppliers for the Pfeiffer Vacuum HiPace 1200 Turbo Pump Package, which is critical for replacing a malfunctioning unit used in a dilution refrigerator. The procurement aims to secure a turbo pump that meets specific technical requirements, including a pumping speed of 1200 l/s for nitrogen, an ultimate pressure of 5 x 10E-10 mbar, and a one-year warranty, with a maximum lead time of two weeks post-order. This pump is essential for generating ultra-low temperatures necessary for metrology experiments in quantum information science, underscoring its importance to NIST's mission. Interested firms are encouraged to submit detailed responses, including company information and capabilities, to primary contact Ranae M. Armstrong at ranae.armstrong@nist.gov or secondary contact Donald Collie at donald.collie@nist.gov, by the specified deadline.
