eDNA Auto Samplers

The Bureau of Reclamation is conducting market research to determine qualified vendors capable of providing eDNA Auto Samplers, with responses due by June 18, 2026; this is a sources-sought notice for planning purposes only and does not constitute a solicitation or commitment.

The procurement calls for two autonomous eDNA auto sampler units capable of collecting water samples for environmental DNA analysis in freshwater environments. Units must feature modular systems supporting filtration, preservation, and water collection with autonomous and tethered operation modes, user-friendly programming interface, and integrated RFID or equivalent traceability with Bluetooth and/or satellite communication. All components must be compatible with standard sterilization protocols (autoclave or bleach).

Performance specifications include maximum eight samples per deployment, operable filter pore size 5.0 micrometers, operating temperature range 0–40 degrees Celsius, lift capability 0–2 meters above water surface, water-resistant enclosure rating IP 43, flow rates 0.1–1.4 liters per minute, and volume measurement accuracy 95 percent. GPS compatibility must support GNSS standards (GPS, Galileo, GLONASS, BeiDou) with approximately 2.5-meter position accuracy. Physical design shall be compact (24–30 inches length, 17–24 inches width, 12–16 inches height) and weigh 100 pounds. Power specifications require 12.8-volt 22.5 ampere-hour Lithium Iron Phosphate rechargeable batteries with minimum three-plus-hour pumping runtime and approximately 30-day maximum deployment duration, plus optional solar panel charging. Deliverables include four total batteries (two per unit), two chargers, two solar panel chargers (if available), intake hoses, connectors, strainers, sterilization filters, two custom carrying cases, and shipping straps. Manufacturer's standard warranty with minimum one-year parts and labor coverage is required.

NAICS code 334516 (Analytical Laboratory Instrument Manufacturing); small-business size standard 1,000 employees. Responses should include business name and address, point of contact with email and telephone, UEI, and business size and type. Email responses to monte_baird@ios.doi.gov.
