SphereJet™ Precision Microsphere System

Product Description

MicroFab has taken three popular ink-jet based microsphere production methods and combined them into a single bench top research platform. Based on MicroFab’s research into ink-jet manufactured drug loaded microspheres, The SphereJet™ system combines drop-on-demand, pressure assisted drop-on-demand, and continuous ink-jet drop formation. Drop generation rates of up to 50kHz and drop diameters of 20 µm to 100 µm can be achieved. With the SphereJet™ system, researchers can develop new materials and protocols based on the solvent extraction/evaporation method of microsphere manufacturing.
