WENDT'S 



ELECTRO-TITRATION APPARATUS 



FOR ACCURATELY DETERMINING THE END-POINT 

 IN CHEMICAL TITRATIONS 



Can be used for Hy- 

 drogen Ion concen- 

 trations (Ph) to the 

 first decimal place, 

 and for preparation of 

 accurately neutral or 

 buffer solutions. 



Can be used in reac- 

 tions involving Aci- 

 dimetry and Alka- 

 limetry, Oxidation 

 and Reduction or 

 Precipitation. 



No. 10312. 



GIVES A TRUE END-POINT 



Regardless of the Presence of Colors, Turbidity, Precipitates, 

 Salts, Weak Acids or Bases
