CARBON DIOXIDE DETERMINATION APPARATUS 



CARBON DIOXIDE APPARATUS, Barker, for the determination of carbonates in limestone, 

 fertilizers, soda baking powders, etc. The outfit consists chiefly of a special hydrometer, in 

 the bulb of which is a reservoir for acid and a reaction chamber for the carbonate. No bal- 

 ances are required, as the change in weight is read directly in percentage of carbon dioxide 

 on the graduated stem. It is suitable for any carbonate containing more than 5 per cent, car- 

 bon dioxide, and permits an accuracy as great as in the standard laboratory method. A cer- 

 tificate of accuracy is furnished with each outfit. Complete with special hydrometer, jar, 

 thermometer, graduated cylinder, dropping pipette, and one pound of hydrochloric acid in 



glass stoppered bottle ; 12.00
