Eight-Stage Non-Viable Andersen Cascade Impactor
First in its class, the Thermo Scientific* Andersen Series of Non-Viable Cascade Impactors is the original design cited as the world's reference for aerosol particle sizing. The impactors are uniquely defined as a primary standard classification device thanks to performance verification through well established fundamental physical principles.
The Thermo Scientific* Andersen Eight Stage Non-Viable Cascade Impactor is a multi-stage, multi-orifice sampler used in environmental working areas to measure the size distribution and mass concentration levels of solid particulates and liquid aerosols. It is cited within the U.S. Pharmacopeia Chapter 601 as the primary standard characterizing device for aerosols within metered-dose and dry-powder inhalers.
