GastroCH4ECK mouthpieces:

Specifically designed with the latest moisture removal and bacterial filtration to remove 99.9% of airborne bacteria from the patient’s breath1.

Facemask adaptor

The facemask adaptor is single-patent-use. A facemask is attached to one end and then the sampling system connects to the breath bags.

Moisture removal filter

For use with the breath bag sampling mode. These will last for approximately 150 samples before it needs to be changed.

GastroCH4ECK breath bags:

Specifically designed to capture as much end-tidal air as possible, with a one-way mouthpiece to prevent loss of sample.

Facemask

Facemasks are single-patent-use and
allow the patient to breathe normally
to produce a breath sample. There are
3 sizes: Large, Medium, and Small.

Calibration gas

The Gastro+ requires calibration
every 3 months using 100ppm H2 gas,
provided as a kit or replacement cylinder.
