This apparatus can be used, however, for 

 testing the viscosity of any form of liquid, 

 besides being adapted for determining the 

 plasticity of all plastic materials for which the 

 initial pressure required is not more than that 

 of a 10 foot water column. 



The above is a simplified form of the appar- 

 atus (also supplied by us), which is recog- 

 nized by the Bureau of Standards as the 

 standard instrument for the determination 

 of viscosity and plasticity. 



The simplified apparatus consists essen- 

 tially of the following^parts : 



2 pipe reservoir for stabilizing 



pressure $8o.oo. 



Water Bath with cover for 



regulating temperature . . . $22.50. 



Plastometer (Viscometer) with 



2 wrenches and key $60.00. 



Besides the above essential parts, auxiliary 

 apparatus may be ordered as desired. 



For information in regard to auxiliary ap- 

 paratus, and for further details, see E & A
