HaB Douglas Bags

The Douglas Bag is an inflatable bag used to collect expired air for the determination of oxygen consumption and basal metabolic rate.

Made of tough, polyvinyl chloride and have electrically welded seams, they are lighter and more flexible than rubber bags and less gas permeable, to minimise measurement errors.

The HaB Douglas Bag Collection System is custom built by our highly skilled technical engineers and can be used in conjunction with either the Hitech or Servomex Gas Analysis units.
