Only the RTube captures the vital biomarker data you need by being available for the subject to use during symptomatic episodes, any time, any place. Monitoring acute airway disease with the RTube allows the capture of biomarkers during exacerbations when the data are most relevant.

Collecting EBC is as easy as breathing through a nebulizer. The subject exhales normally into the RTube while the moisture from their breath is condensed in the collection chamber. After collection, the chamber is sealed, stored locally, or transported to a lab for analysis. At the lab our unique internal one-way valve is used as a syringe that gathers droplets adhering to the inside wall into a sample pool near the top of the RTube where it can easily be removed and analyzed.

Available as a starter kit with plunger and cooling sleeve.
