This is a $69,367.35 firm-fixed-price purchase order awarded by the National Institute on Drug Abuse (NIDA), a civilian agency, to Phenosys GMBH, a Berlin-based R&D company, for a PhenoSys JetBall Virtual Reality System for Mice. The award, which has no set-aside designation, is for a basic setup of the VR system with TFT screens and supports the agency's research into freely moving mice with head-fixed capabilities. This award is the most recent in a series of prime federal contracts Phenosys GMBH has received from various NIH institutes and centers to provide specialized research equipment, including RFID systems, VR imaging systems, and mouse treadmills. The original procurement was an unrestricted sources sought notice focused on acquiring a VR system that enables flexible experimental environments, allows mice to remain stationary while interacting with a virtual world, and supports correlating animal activity with external measurement data.
