Attachment 2-Specifications.docx

This is a Specifications attachment document for a federal procurement of laboratory equipment. The USDA Agricultural Research Service seeks one blackbody unit with absolute temperature control and emissivity greater than 0.99 to replace an obsolete Electro Optical CES100-06/CF/MG model. The blackbody must meet minimum technical requirements including 120 VAC power, a 300 mm x 300 mm target surface area, operating temperature range of -5°C to +50°C, thermal uniformity of ±0.2°C, target emissivity of ≥0.99 (noted as critical), temperature measurement accuracy of ±0.03°C, remote control capability via Ethernet/RS232/IEEE488, and heating/cooling slew rates exceeding 0.5°C/s and 0.2°C/s respectively. The unit must be delivered within 60 days after award to the USDA-ARS Conservation and Production Research Laboratory in Bushland, Texas, and include a 12-month warranty. Installation support will be provided by USDA personnel during normal business hours (Monday–Friday, 0800–1630 CDT, excluding federal holidays).

Quotations must be submitted by July 30, 2026, at 9:00 AM PT to Elizabeth Calhoun at Elizabeth.Calhoun@usda.gov, with questions due by July 27, 2026, at 2:00 PM PT. Vendors must submit firm fixed-price quotes on company letterhead valid for at least 60 days, completed SF-1449 forms with full contract line item pricing, SAM.gov UEI, and capability statements or technical documentation demonstrating compliance with all specifications. All items must include place of manufacture information. The government intends to award without discussions but reserves the right to conduct discussions if deemed necessary. Failure to demonstrate compliance or submit all required documentation will result in quote rejection without further discussion.
