Rot WW Sterilizers 
Nos. 2196-8 
Hot Air Stcrilizef, Lautenschlaegfer Pattern. — These ovens are thoroughly- 
well made and strongly constructed. They are made of the best Russia iron, 
covered with enamelled asbestos. They are intended for laboratory work, where 
economy of gas and time is a sine qua non. They will heat apparatus placed 
inside much more rapidly than any other sterilizer made, on account of the rapid 
reverberation and circulation of heated air in all parts of the interior of oven. 
The walls do not get so hot as the ordinary oven. There is, therefore, less danger 
of burning cotton. (The circulation of heated air inside the double wall does not 
communicate with the directly heated air from the row of small bunsen burners 
which surround the oven.) These ovens can be heated to 150° C. in fifteen 
minutes.
