Halo Labs manufactures scientific equipment for pharmaceutical particle analysis. The Horizon is their flagship product and detects particles in the range of 2 microns to several millimeters. Particulate matter is ubiquitous in biopharmaceutical formulations and is the most common reason for FDA-mandated pharmaceutical recalls (nearly 16 million units recalled in 2014). The FDA tightly regulates these particles due to the possible adverse side effects. The Horizon measures these particles more accurately, and faster than any other technology and uses far less precious sample volume. Halo Labs was founded in 2011 and is located in Philadelphia, PA.
