Scientific Instrument Supply – Laser Diffraction Particle Size Analyzer

A new off-the-shelf laser diffraction particle size analyzer with an integrated wet dispersion unit is being procured under a small business set-aside subcontract, with the requirement that the instrument includes a reverse Fourier lens, a 3500 rpm pump, and 40W sonication capability to ensure precise and reliable particle sizing across diverse sample types. The supplier must guarantee ten years of parts availability to support long-term operational continuity and minimize downtime for the end user, which is critical for maintaining consistent analytical performance in research or regulatory environments. The contract is administered by the Department of the Interior at the Denver Federal Center and is subject to the Federal Acquisition Regulation’s Total Small Business Set-Aside provisions, restricting participation to qualified small businesses. Proposals must be submitted by April 29, 2026, by 9:00 PM, under the NAICS code 334516 for analytical laboratory instruments, with the award expected to support scientific operations requiring high-accuracy particle characterization.
