Kryptol Combustion Furnaces for Elementary Organic Analysis 



Kryptol furnaces are heated by passingf the electric current through a resistant, 

 granular mass, the Kryptol. No wires, except the conduits, are used in this furnace. 

 Therefore, no burning out of wires possible. The heat can be quickly raised above 2000° 

 C, can be variated in different parts of the furnace, depending solely on the thickness of 

 the Kryptol mass.
