The Coriolis µ bio-air sampler is used at the Pasteur Institute for virus collection in laboratory and hospital conditions. The Pasteur institute is an international research institute of excellence and renowned for its virus studies. In order to analyze the airborne transmission of viruses, the Coriolis air sampler has been used under laboratory conditions and in hospitals. The Coriolis is a biological air sampler capable of collecting pathogenic agents such as viruses. The system is based on cyclonic technology and the biological particles are concentrated into liquid, which can be analyzed by any downstream methods. The analysis results are then obtained in a few hours. The results are used to set up the counteract to fight against the spread of the virus.
