GLAS-COL HEATING MANTLES for safe heat, easily controlled
%
#
Safety is a watchword in t h e modern laboratory. T h e elimination of open burner flames for heatingis imperative if t h e potential danger of fire or ex plosion is t o be reduced. Glas-Col Heating Mantles are t h e perfect modern method, used in thousands of well-appointed labs because they heat safely and efficiently. Accuracy, too, is a requisite of present-day research, also in temperature control. T h e use of a suitable voltage regulator, coupled with t h e excellent heating and insulating qualities of Glas-Col Mantles, makes temperature regulation simple, yet precise. Use Glas-Col Mantles for every heating problem. Scientific Glass maintains ample stocks of all sizes and types for prompt delivery. A detailed bulletin will be sent on request.
