- Includes shipping/import costs/handling, a warranty of at least one year from completed installation, onsite installation, training, testing, and verification.

Period of Performance
Delivery must be within 30 days ARO.

Place of Performance
National Center for Agricultural Utilization Research, 1815 North University Street, Peoria, Illinois 61604.

Bidder Requirements
Bidders must meet the requirements for a Total Small Business Set Aside. Offerors providing 'or equal' items must include descriptive literature demonstrating compliance with salient characteristics. The equipment must be compatible with existing Bruker Mq20 systems. Rotunda Scientific Technologies is the only known authorized distributor.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a closely related prior contract, with Bruker Biospin identified as the awardee under solicitation/contract 1232SA26P0604 for a time-domain nuclear magnetic resonance (TD-NMR) body composition analyzer valued at $184,494 (08/28/26–02/26/27). The current requirement is also for a Bruker Brand Minispec mq20 TD-NMR system with variable temperature capability and associated calibration/sampling and software compatibility, suggesting the prior work likely involved supplying and configuring TD-NMR equipment that is similar in type and intended use.
