The Department of Health and Human Services, specifically the National Institutes of Health (NIH) and its National Institute of Allergy and Infectious Diseases (NIAID), is seeking information on domestically manufactured spectrophotometers through a Sources Sought notice. The objective is to identify products that enhance measurement accuracy and facilitate the early detection of contaminants in laboratory settings, thereby improving data efficiency and reliability. These spectrophotometers will be utilized to determine protein and DNA concentrations, measure optical density, and analyze absorbance spectra, which are critical for various laboratory applications. Interested vendors must submit a capability statement by January 27, 2025, at 5:00 PM EST, detailing their qualifications and confirming that their products are manufactured in the United States. For further inquiries, vendors can contact Jessica Emerson at jessica.emerson@nih.gov or Jesse Weidow at weidowjd@niaid.nih.gov.
