Borosilicate glass, graduated. For the demonstration of the
chemical composition of water by volume and the
electrochemical equivalent of hydrogen by electrolysis of water.
Platinum electrodes mounted in rubber stoppers are used for the
electrolysis of acidified water but carbon electrodes must be used
for ammonia solutions or hydrochloric acid (or another chloride
containing solution). Stopcock and reservoir at apex of outer
tubes and inner tube respectively. Outer limbs graduated 0-50 x
0-2 ml.
