eFIT Lab is a system for the inactivation of pathogens in a liquid solution up to a depletion level of > 6 log reduction. By using low-energy electron irradiation, the genetic material is reliably destroyed. Its main applications are in vaccine production and processes ranging from selective degradation to the complete inactivation of infectious pathogens. Other potential applications address contamination control strategies including pathogen depletion in process media and blood-derived products, as well as cell therapeutics.
