R-Tube

Exhaled breath condensation is a non-invasive method of gathering exhaled breath samples useful for assessing a number of disease parameters.

The R-Tube is designed to provide maximum sample collection in minimal time. Exhaled air is directed through a unique one-way valve and into a cooled collection chamber where vapors, aerosols and moisture in the breath condense along the protected inside walls of the R-Tube.

The one way valve is then used as a plunger that collects droplets stuck to the inside wall and holds the sample near the top of the R-Tube.

The simplicity and environmental flexibility of R-Tube offers the potential for rapid development of clinical diagnostics utilizing EBC pH and other biomarkers.
