The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is seeking to procure a brand name Air-jet sieve shaker essential for the separation of micro and nano-plastic (MNP) test materials, specifically targeting particles under 10 µm. This procurement is critical due to the increasing demand for MNP test materials in environmental research, which often struggles to obtain pure samples without extensive processing. The required equipment must include features such as air jet technology, digital adjustments for process parameters, and the capability to produce two fractions using a cyclone, with delivery expected within 90 days of contract award. Interested vendors should submit their quotations by September 19, 2024, at 1:00 PM EST, and can direct inquiries to Erik Frycklund at erik.frycklund@nist.gov or by phone at 301-975-6176.
