Opportunity Overview
The Centers for Disease Control and Prevention has posted a notice of intent for Component Repair and Calibration, 75301-26-Q-79276, covering repair and calibration of three Government-owned Aerodynamic Particle Sizers.
Deadline
Responses are due September 21, 2026 at 10:00 AM Eastern Daylight Time.
Scope
CDC intends a sole-source firm-fixed-price purchase order to TSI Incorporated for repair and calibration of three Aerodynamic Particle Sizers. The notice states that proprietary operating models, internal flow-regulation knowledge, and access to components behind embedded electronics are required. The expected turnaround is 21 days.
The work includes restoring each instrument to a 5 liter-per-minute calibration flow rate, maintaining that flow under inlet pressure drop, and calibrating particle number-size distribution performance across approximately 0.37 to 20 micrometers aerodynamic diameter using time-of-flight measurement and the instrument’s optical coincidence-detection system.
Competition
This is a notice of intent to sole source rather than a general competitive solicitation. It is classified under NAICS 811210, Electronic and Precision Equipment Repair and Maintenance, and PSC J066, Maintenance/Repair/Rebuild of Instruments and Laboratory Equipment. Any alternate source must satisfy the live notice’s capability and submission requirements.
Funding / Contract Value
No fixed maximum contract value is stated in the public notice.
