SASS 3010 Particle Extractor
The SASS 3010 Particle Extractor is the perfect companion product to the SASS 3100 sampler or SASS 4100 filter-based concentrator. It extracts and transfers aerosols captured by Research International’s electret filters to a small fluid volume suitable for sample analysis. Extraction efficiencies are typically in the range of 60‑80%.

SASS 4000 Concentrator
The SASS 4000 is a highly efficient, high-volume aerosol concentration device that processes large volumes of ambient air. It continuously transfers particulates from the primary air stream to a much smaller secondary air flow, creating concentrations 4X to 15X higher than present in the incoming air. Can be connected to a SASS 2300 or other device.

SASS 4200 Vehicle-Mount Concentrator
A highly efficient, high-volume aerosol concentration device designed for vehicular applications. A blower-driven concentration device inside the unit pulls air in at a rate of about 3600 LPM. Particulates in the sampled air are transferred to a low flow-rate secondary loop that can be routed to a location inside the vehicle.
