The Department of Defense, through the Army Medical Research Acquisition Activity, is planning to award a sole source contract to World Precision Instruments, LLC for the procurement of two Epithelial Voltohmmeter (EVOM) Auto V3 systems, which are critical for Transepithelial Electrical Resistance (TEER) measurement in cellular activity research. This specialized equipment is essential for real-time measurement using a 24-well plate format and includes installation, training, and a two-year warranty. The urgency of the research activities at the U.S. Army Medical Research Institute of Infectious Diseases necessitates this procurement, as alternative vendors would cause unacceptable delays. Interested entities that believe they can meet the specifications are invited to submit evidence of their capability by May 24, 2025, at 12:00 PM Eastern Time, with inquiries directed to Lindsey Arthur at lindsey.b.arthur2.civ@health.mil.
