EVOM TEER Measurement System

The Defense Health Agency has issued a Special Notice concerning the procurement of two Epithelial Voltohmmeter (EVOM) Auto V3 Transepithelial Electrical Resistance (TEER) Measurement Systems through a potential sole source contract. The notice, published on May 9, 2025, involves a specialized scientific equipment acquisition from World Precision Instruments, LLC (WPI). The equipment is designed to measure cellular activity in real-time using a 24-well plate format and includes specific technical requirements such as automation capabilities and compatibility with Corning 24-well plates. The solicitation falls under the NAICS category of Analytical Laboratory Instrument Manufacturing (334516) and is being managed by the United States Army Medical Research Acquisition Activity (USAMRAA). WPI has been identified as the sole vendor capable of meeting the Minimum Essential Characteristics (MECs) specified in a previous Request for Information (RFI).

The primary objective of this Special Notice is to provide an opportunity for potential alternative vendors to demonstrate their capability of fulfilling the contract requirements before a sole source award is made to WPI. Contractors have until 12:00 PM Eastern Time on May 24, 2025, to submit written responses with compelling evidence of their ability to provide the required EVOM TEER Measurement Systems. Eligibility is open to vendors who can meet the detailed technical specifications and demonstrate equivalent or superior capabilities to WPI's offering. If no competitive responses are received that meet the specified criteria, the contract will be awarded to WPI without further competition. The proposed contract includes on-site installation, training, and a two-year warranty from the delivery date. Interested contractors must carefully review the technical requirements and be prepared to provide comprehensive documentation proving their system's alignment with the specified Minimum Essential Characteristics. The contract represents a targeted procurement for specialized scientific research equipment critical to cellular activity measurement.
