Abstract: Devices, systems, and methods are disclosed which relate to using a use large area surface sampler with invertible bag for collection of biological and non-biological particles prior to subsequent analysis. The large area surface sampler with invertible bag uses an inverted bag with bonded sampling material to first serve as a sampling device followed by the bag being turned right side out and the captured particles being extracted inside of the bag. The device includes measures for sealing liquid in the sampling material using a protective cup at time of manufacture. This enables users to simply remove the protective cup and perform wet surface sampling prior to turning the bag right side out and removing captured particles from the sampling material with repeated compressions.

Abstract: The present subject disclosure discloses devices, systems, and methods related to collection and recovery of Aerosols and Bioaerosols for analysis. The system includes an omni-directional inlet assembly that is easily removed for decontamination and can be replaced with an already clean inlet assembly or with directional inlets or other tools for collection from animal breathing zones, air ducts, air nearing moving vehicles and other sampling scenarios. Further, the system includes other features that enable the device to be lower in cost than other similar systems while providing improved usability and performance.
