Before you can study it, you have to capture it.

SARS-CoV-2

Coronavirus - is it airborne or not? How far can it travel? Is the recommended six feet of "social distance" really enough? To answer questions like these, you need the best collection devices. Our SASS 2300 wetted-wall cyclone air samplers are being used in hospital wards in Wuhan, China to study these questions and more. (And no, six feet is probably not enough.) Read more below:

SASS 2300® Air Sampler Collects Key Information in Wuhan Study

A SASS 2300 wet air sampler in use in a hospital COVID-19 ward in Wuhan, China, April 2020.
Hospital staff in Wuhan using a SASS 2300 Wetted-Wall Air Sampler to study movement of SARS-CoV-2, the virus that causes Covid-19.

The CDC's monthly journal Emerging Infectious Diseases has published an online early release of a study which suggests that six feet is not nearly enough “social distance.” Using a Research International SASS 2300 air sampler in hospital wards in Wuhan, China, the authors found that airborne Coronavirus virions can travel as much as four meters, or about 13 feet.

NEW: Disinfectant products for SARS-CoV-2

Spectra DF-500 Disinfectant kills SARS-CoV-2

Research International now offers two powerful yet safe disinfectants. Both are tested and proven to kill SARS‑CoV‑2, but are safe for people, property, and the environment.


Spectra DF-500 two-part disinfectant destroys bacteria, viruses, algae, and fungi.

Spectra DF-200 three-part disinfectant destroys the same harmful pathogens as DF-500, and also neutralizes toxic chemicals.

SASS® Air Samplers: Relied on by Scientists Everywhere

Our SASS 2300 and SASS 3100 air samplers are in use around the world wherever researchers are studying airborne pathogens. Some typical applications include study of the air in subways, outdoor air in polluted urban areas, meat processing plants, waste water management plants, and livestock and poultry farm facilities.
