Turbomolecular Vacuum Pumps

The National Institute of Standards and Technology seeks six turbomolecular vacuum pumps in three configurations to support its Surface and Trace Chemical Analysis Group, with proposals due September 21, 2026. This is a Total Small Business set-aside (NAICS 334516, 1,000-employee threshold).

Place of performance and delivery are to NIST's Gaithersburg, Maryland facility (100 Bureau Drive, Building 301). The procurement requires two 67 L/s pumps with DN 63 ISO-K inlets, two 260 L/s pumps with DN 100 ISO-F inlets, and two 685 L/s pumps with DN 160 CF-F inlets. All pumps must be fully interoperable with Ametek Cameca ims 1280 and ims 1300 large-geometry secondary ion mass spectrometers with no modifications to existing vacuum housing or electrical connections. Each pump must include an integrated controller with RS-485 serial communication ports compatible with Pfeiffer Vacuum Protocol, power cables, air cooling, and an Operations Manual.

The solicitation was amended on September 17 to extend the delivery requirement from 60 days to 20 weeks from award date. Standard commercial warranty commences upon Government acceptance. NIST will conduct visual inspection and functional testing upon delivery, with acceptance confirmation within one week. The Government retains sole discretion to reject, repair, or require replacement of nonconforming items at no cost to the Government.

Award will be made to the responsible quoter submitting the lowest-priced, technically acceptable quotation. Quoters must submit technical compliance documentation, firm-fixed pricing, active SAM.Gov registration, product manufacturer location information, and completed solicitation provisions. Payment is made via the Invoice Processing Platform upon delivery and acceptance.
