Flow imaging (FI) instruments photograph a liquid as it flows through a cell and count, size and classify subvisible particles from the images. Particle shape helps separate protein aggregates from silicone oil droplets and air bubbles, so FI is used alongside light obscuration as an orthogonal method. Buyers compare size range, sample volume, magnification, classification software and combined LO modules. This page lists the products we track and their makers.
