USDA - Kellogg Soil Survey Lab - Particle Size Distribution Analyzers

The USDA Farm Production and Conservation Business Center, acting on behalf of the Kellogg Soil Survey Laboratory in Lincoln, Nebraska, has issued a sources-sought notice to identify qualified vendors capable of providing three laser diffraction particle size distribution analyzers and associated accessories. The objective is to enhance the laboratory’s capacity to process approximately 8,000 soil samples under the Regenerative Pilot Program, with a goal of achieving operational readiness by mid-December. The analyzers must meet precise technical specifications including a particle size range of 0.01 to 3500 micrometers, compatibility with Mastersizer 3000/3000+ wet dispersion units, blue LED enhancement at 470 nm, an optical bench length of 690 mm, and full automation of dispersion, cleaning, and dispersant filling. Each system must include a 600 mL sample tank, 40W inline sonication, and pumping capabilities up to 2.3 L/min, with all hardware required to seamlessly integrate with existing KSSL infrastructure to ensure data consistency. Delivery of the three units is required within 180 days of order receipt, and the sole place of performance is the Kellogg Soil Survey Laboratory at 1121 Lincoln Mall, Room 230, Lincoln, NE 68508.
