4746 Gas Burette, Franke's, modified form 



This burette is the results of long practical experience in the analysis of gases, and will be found to be simple, 

 reliable, convenient, and capable of rapid manipulation. It permits of the reagents being used a second time, 

 requires no stand, no pressure reservoir, no three-way stopcock, and in the handling the loss of gas is avoided. 

 Dr. Franke states that an analysis of gas can be completed with it in fifteen minutes. Being small and compact 

 it is thoroughly under control. 



DESCRIPTION. 



A measuring cylinder widened at upper end, where it is closed by a stopcock. Graduation, 100 cubic 

 centimetres. 



Receiver or reservoir for reagents joined to the graduated part by a stopcock with wide bore and closed 

 at lower end by a plug or stopper provided with a stopcock. 



The wide bore of stopcock between A and B and the plug closing c facilitates the filling and emptying ot 

 burette. The o point of the scale lies in the bore of the stopcock b. The capacity of the measuring part, including 

 stopper bore, is exactly 100 cubic centimetres.
