The U.S. Department of the Interior, specifically the U.S. Geological Survey (USGS), is seeking quotes for a new dual auto titration instrument to replace an outdated model used for analyzing alkalinity and acidity in aqueous samples. The instrument must be new, capable of accurately handling small sample sizes, and compliant with EPA methods for titration, featuring automatic rinsing systems and a sample tube rack, along with a service and maintenance package post-installation. This procurement is crucial for maintaining efficiency in the Mineral Resources Program and Earth Mapping Resources Initiative, and it is set aside exclusively for small businesses under NAICS code 334516. Interested vendors should submit their quotes and any inquiries to Mary (Beth) Wilson at bwilson@usgs.gov by the specified deadlines outlined in the solicitation document.
