SASS® 2300

Wetted-Wall Air Sampler

SASS 2300 Wetted-Wall Air Sampler

The SASS® 2300 Wetted-Wall Air Sampler extracts airborne pathogens, particulates, bacteria and spores in liquid form for later analysis. Its patented wetted-wall aerosol collection method has earned U.S. Department of Homeland Security Certification under the U.S. Safety Act of 2002.

The SASS 2300 offers extremely long sampling protocols – up to several days – and unsurpassed monitoring capabilities in environments ranging from farmyards to hospitals to battlefields. Wireless control options and customizable sampling protocols extend its versatility.

The SASS 2300 has been successfully used to detect the airborne viral pathogens that cause exotic Newcastle disease and hoof-and-mouth disease, as well as strains of avian flu virus in California commercial poultry flocks.*
