Description
The Freas gas generator, designed by Prof. Freas of the Kent Chemical Laboratory at the University of Chicago, was advertised as an “effective, cleanly, economical method of obtaining any gas desired for use.” Thomas B. Freas (1868-1928) also developed an oven suitable for chemical and biological experiments.
