Made of Borosilicate glass. 

For use in demonstrating decomposition of water, determination of chemical composition by electrolysis and applicable in evaluation of electrochemical equivalent of hydrogen. 

The glass unit has two connected limbs, graduated for 50 cm³ capacity, integral with reservoir tube and funnel shaped bulb, with a stopcock at top of each limb, with one pair platinum electrodes and one pair carbon electrodes. 

Platinum electrodes are used for the electrolysis of water; Carbon electrodes for the electrolysis of ammonia or hydrochloric acid. 

Reservoir capacity 200cm³. Without stand. 

Overall Dimensions: 700 x 85mm (Ht.xW)
