In 1928, he designed a Barcroft-Warburg apparatus for tissue respiration studies.

Troxipide accelerates oxygen intake of marginal gastric mucosa and glycogen consumptive stimulation of the gastric mucosa of the corpus, thereby elevating the tissue respiration and energy metabolism.

An example of the importance of the field to post-harvest handling is the discovery that ripening of fruit can be delayed, and thus their storage prolonged, by preventing fruit tissue respiration.
