NIH intends to issue a non-competitive, firm-fixed-price purchase order to SPT Labtech for a 12-month preventative maintenance and Reliance Service Agreement covering two Mosquito nanoliter liquid handlers. The requirement is sole-source because SPT Labtech is the OEM and the only provider capable of supplying OEM-certified service, genuine parts, factory calibration, and proprietary software upgrades needed to maintain equipment precision. The associated NAICS code is 811210, with a $34.0 million small business size standard, and the requirement is not set aside for small business. The applicable Federal Acquisition Circular is 2026-01, effective March 13, 2026.
