The TE-BC251 wearable multi-stage bio-aerosol collector is a specialized device designed for the collection of airborne viruses, such as Influenza and COVID-19. This device was developed by the National Institute for Occupational Safety and Health (NIOSH) and manufactured by Tisch Environmental. The TE-BC251 is a cost-effective and high-quality cyclone that is well suited for quick deployment in response to rapidly evolving situations. The multi-stage cyclone design allows for the collection of bio-aerosols in one of three compartments, enabling accurate retrieval of samples at multiple cut points. This device can be worn by individuals for personal sampling, making it an ideal tool for occupational health and safety applications.

The TE-BC251 cyclone sampler is designed to collect bio-aerosols, including airborne viruses such as influenza and COVID-19. It has a flow rate of 3.5 L/min, which meets the ACGIH/ISO criterion for separating respirable and non-respirable airborne particles, making it suitable for health-related aerosol measurements. The BC 251 has been used effectively to collect influenza virus from coughs of infected patients as well as in healthcare facilities. The sampler can be used with commercially available personal air sampling pumps.
