The Micro Flow Imaging (MFI) platform is a bright-field microscopy based particle analyzer. The MFI accurately counts and characterizes visible and sub-visible particles (silicone drops, glass, protein aggregate) according to their optical properties. The MFI's unique capability to detect and characterize sub-visible particles is recognized as a breakthrough technology for particle analysis by protein therapeutics formulation and process optimization scientists world wide . MFI is also the world's first automated particle analysis platform. The automation of the MFI minimizes the set-up time and allows unattended operation.
