Dark field microscope Olympus BX53 Microscope & DP75 Camera

The Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is soliciting quotations for a laboratory-grade Dark Field Microscope Olympus BX53 system with DP75 Camera and associated components under Request for Quotation (RFQ) 12639526Q0084. This commercial item acquisition is being conducted under FAR Part 12 procedures and requires the delivery of a complete microscope system consisting of 16 line items, including the microscope frame, LED light source, darkfield condenser, trinocular head, eyepieces, three objective lenses (10X, 20X, and 40X), mechanical stage, and DP75 camera with USB 3.1 connectivity. The equipment must be compatible with Windows 11 and interface with CellSens imaging software to ensure integration with the laboratory's existing information management system. Evaluation will be based on technical specifications compliance and lowest price for a technically acceptable solution (LPTA), with past performance also considered. Quotations are due by March 30, 2026, at 5:00 PM Eastern Time, with technical questions due by March 26, 2026.

This is an unrestricted acquisition with no small business set-aside, though the justification document identifies Evident Scientific and its authorized resellers as the intended source, with Government Scientific Source Inc. noted as an alternative source. All items must be brand-name Olympus/Evident products that are new, not refurbished or remanufactured, with clear traceability to the original equipment manufacturer or authorized distributors. The contract will be awarded on a firm fixed-price basis with delivery required within 90 days of award to the USDA Center for Veterinary Biologics at 1920 Dayton Avenue, Ames, Iowa. Offerors must submit pricing for all items and maintain price firmness for 90 calendar days from the quotation submission date. No specific budget range or award value is disclosed in the solicitation; however, the equipment is essential for the Center's potency testing and documentation of reagent results, indicating institutional criticality rather than experimental procurement.
