SUMMARY—A multi‐unit rigorometer has been developed to (a) make it possible to study extensibility (isotonic) and tension (isometric) changes in several muscles (red and white) simultaneously, under identical conditions, (b) make it possible to control the environment (aqueous or gaseous) around each of several muscle strips being monitored simultaneously and (c) facilitate additional biochemical studies of isotonic and isometric parameters of fresh and/or glycerinated fibers. The rigorometer is an enclosed, temperature controlled, environmental chamber designed specifically for studies on strips of parallel muscle fibers. The chamber will accommodate six muscle strips of varying sizes and has a wide adjustment for degree of sensitivity. Small cylinders have also been specially designed to facilitate separate controls of aqueous and gaseous environments surrounding each muscle strip. This multi‐unit rigorometer is a further development of the rigorometer originally described by Briskey et al. (1962). The details of the design and application of this rigorometer are disc
