Respiration Apparatus, Closed Circuit, 1945
Miniature water-seal spirometer used with a close-circuit system for measuring oxygen uptake in small animals. The animal(s) to be studied were placed in the small chamber at the right. A blower motor moved air from the chamber through a soda-lime absorber (not shown) and the overall volume of the system was monitored by the spirometer. The spirometer was identified as a Benedict-Roth-Collins. From Bioenergetics and Grown by Samuel Brody, Published by Reinhold Publishing, NY, 1945. Chapter 12, page 330.
