$PBIO announced the achievement of a critical milestone: the lock-in of final design specifications for the commercial production model of its proprietary, next-generation Ultra Shear Technology™ ("UST™"-based nanoemulsification system. Following achievement of this milestone, the Company has begun to build the initial "Alpha" unit of the commercial model. Once built, tested, and approved, the Company will immediately proceed to build an additional 15 ready-for-sale systems, thus enabling PBI to meet its goal of shipping the BaroShear K45 UST System in early (Q1/Q2) 2021.
