Samples were removed and assayed at 22C at selected time intervals. This instrument provides eight independent selectable temperatures with a high degree of accuracy and stability across a range of ambient temperatures. The instrument construction costs were equivalent to the purchase price of a single refrigerated circulating water bath, yet provided the flexibility required for simultaneous investigations across a range of temperatures above and below ambient temperatures on a single instrument. These are only a few of the myriad of potential applications of this instrument in the study of the sensitivity of plant and animal metabolism to varying temperatures. References Arnon D.I. 1949.
