Research International has developed a full line of both wet and dry air samplers to work in the most demanding environments: from research institutes, to public health facilities, to nuclear power plants to homeland security.
 SASS 2300 Wetted-Wall Air Sampler
Extremely long collection periods continue to be a product highlight. Sample fluid is maintained at a
constant amount independent of collection time, ambient air temperature, or relative humidity, providing
unsurpassed monitoring capabilities in environments ranging from farmyards to hospitals to battlefields.

 SASS 2400 Low-Volume, Wetted-Wall Air Sampler
Designed to operate with a much lower air flow and fluid sample volume than the SASS 2300, while
still employing the highly successful (and patented) wetted wall aerosol collection strategy that has received U.S.
Department of Homeland Security Certification under the U.S. Safety Act of 2002. . .

 SASS 2400 OEM Version
A minimum-parts version of our smallest wetted wall aerosol particle collection system. It is supplied as
a partially-assembled kit without case. The kit is less costly and allows users to integrate Research
International's smallest sampler into a custom aerosol collection system. . .

SASS 4000 Preconcentrator
A highly efficient, high-volume aerosol concentration device that processes large volumes of ambient air, continuously transferring particulates from this primary
air stream to a much smaller secondary air flow. As a result, the secondary flow can reach aerosol
concentrations that are 4X to 15X higher than present in the incoming air. . .

 SASS 3010 Particle Extractor
Used to extract and transfer to a small fluid volume, aerosols captured by Research International’s
electret filters. Extraction efficiencies are typically in the range of 60 to 80%.

 SASS 4100 Two-Stage Aerosol Collector
Builds upon the design of the SASS 4000 Concentrator by directing the secondary air through and electret bulk filter media from which the particles can later be extracted for detection and analysis . . .
