Thelco Bacteriological Incubators 



Electrically Heated and Controlled 



Thelco Bacteriological Incubators are built of well seasoned heavy oak, 

 finished inside and outside with white paint enamel. This finish imparts 

 to the incubators a handsome and clean appearance. An inner door of 

 glass is provided to allow inspection of the chamber without opening the 

 door. No water jacket is used or required. 



An exclusive feature is the removable wire resistance heating plate. 

 This method of heating is distinctly superior to lamps in that it 

 evenly distributes the heat throughout the chamber; furthermore, it will 

 not burn out to cause spoilage of cultures, annoyance and inconvenience, 

 that is so apt to happen when lamps are employed as a heating medium. 



The Thelco bi-metallic Thermostat employed will maintain the temper- 

 ature constant to within a degree without any attention after adjustment 

 is once made. 



The Operation is Very Simple 



To place the incubator in use, it is only necessary to screw the attachment plug into an 

 electric light flocket and ttirn on the current; then adjust the regulator until the thermometer 

 reaches the temperature desired, which will remain constant to within a degree. The incu- 

 bator can be operated on direct or alternating current. 



When ordering please state voltage of current. 



Each Incubator is supplied with perforated metal shelf (Nos. 4 to 7 with two shelves) and 

 cord with plug ior attaching to regular electric lamp socket.
