DESCRIPTION 



This Pattern Wasserman Bath which has been adopted as the Standard for the 

 United States Army, is most economical in operation. 



The Water Vessel which measures 30"x23"xl2" deep, on the standard size, per- 

 mits the use of a very large volume of water. Being surrounded by a Case of 

 Polished Rust Resisting Iron, lined with a heavy layer of asbestos, the water holds 

 its temperature with the minimum expenditure of heat. A single Micro burner being 

 sufficient for this large bath when gas is used. 



The only part exposed to the air is the lid. 



The Lid is made double the outer, or top being flat, the inner lid sloping to rear. 

 The condensation which forms on the outer lid falls on the inner lid, flowing to 

 the two rear corners prevents any dripping of water into the Tubes from injuring 

 the specimens being tested. 



There is furnished with each bath a Thermometer, also a Gas Thermo Regulator 

 and two Micro Burners. 



The Constant Level which maintains the correct height of water in the bath is 

 very simple, and easily connected with two rubber hose, one from the water supply 

 and the other to the waste pipe. The use of this feature is optional. The amount of 

 water evaporated being very little. 



When Electric Equipment is ordered with this, we furnish an Electro Regulator 

 of the best make and all necessary connections, Lamp Switch, etc., to use on either 

 110 or 220 volts. 



The racks furnished, 20 in number, are marked from 1 to 200, are the Standard 

 Army Medical School Wasserman Type.
