AUTOCLAVES 



AUTOCLAVES, Steam Pressure Sterilizers, horizontal form, for rapid sterilization. Constructed 

 of heavy polished copper with double wall. Mounted on substantial iron stand which can bo 

 permanently fastened to the floor. Below the sterilizer is a detachable steam generator which 

 eliminates any danger of burning out the sterilizer should the water be entirely used up. The 

 autoclave may be ordered without generator by those who possess a source of steam free from 

 impurities. The circular door, made of solid cast brass, is quickly and easily opened, rolling 

 back on a track inside the sterilizer. The door and head are perfectly ground and fitted, 

 requiring no packing or gaskets to make a steam tight joint. No clamps or springs are re- 

 quired to hold the door shut, as it cannot be opened if the least steam pressure remains in 

 the chamber, thus eliminating the danger of scalding. The steam enters, circulates around 

 the inner jacket and is then admitted to the inner chamber through an automatic valve, the 

 air being expelled through an air cock. The safety valve is set to relieve at 15 pounds pres- 

 sure. The autoclave may be used as a free steam sterilizer by leaving the air cock open, 

 thus insuring a temperature of 100C. inside the inner chamber. Complete with inner shelf, 

 water gage, safety valve, steam gage and generator.

AUTOCLAVES, Horizontal Type, of double cylinder form with steam space entirely surround- 

 ing the inner chamber except at entrance door, thus reducing condensing surface to a mini- 

 mum. By this arrangement the inner chamber becomes perfectly dry within a brief time 

 after withdrawal of steam. A special control valve at the side with dial and indicator, per- 

 mits the operator to regulate easily the admission or withdrawal of the steam or air from 

 the inner chamber. The independent generator can be easily taken apart for cleansing and 

 repairs. The autoclave is constructed of copper and brass, except the door, which is of
