Over 400 Published Studies Performed Using RTube™
The Standard in Exhaled Breath Condensate (EBC) Collection Devices
Celebrating 25 Years in Breath Research
Our RTube Breath Condensate Collection Device has been used over 230,000 times to sample exhaled aerosols and VOC’s for the study of airway biomarkers in academic, pharmaceutical, and government research studies since 2000.
No other company has continuously supported the breath research community as long as we have, and we are very proud to have earned the trust of researchers worldwide. From product innovation to protocol development to logistical support, we’ll help you get the best possible study results.
