HaB Douglas Bags

One of HaB Direct’s most popular branded products is its Douglas Bag.

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.
