Hoffman Voltameter

Product Description. The Hoffman's Voltameter is used for demonstrating the chemical composition of water by volume and the electrochemical equivalent of hydrogen by electrolysis of water.

For demonstrating decomposition of water. This design is prefer red for work of best precision.Platinum electrodes are used electrolysis of water.The electrodes are mounted with rubber stoppers for insertion in the open ends of the voltmeter limbs. The unit has two connected limbs, integral with reservoir tube and funnel shaped bulb, with a stop clock at the top of each limb. with suitable metallic stand, helps to prevent accidental breakage.Glass parts are made from corning glass

Our immaculate range of Hoffman's Voltameter is highly demanded in the market by customers which are designed using excellent metal, provides exceptional durability level with long lasting feature. Its used for the electrolysis of ammonia or hydrochloric acid with carbon electrodes.

For demon. of the decomposition of water, determination of chemical composition by electrolysis and with applications in the evaluation of the electro chemical equivalent of hydrogen. Its used for the electrolysis of ammonia or hydrochloric acid with carbon electrodes. The electrodes available separately are mounted in rubber stopper for insertion into the open ends of the voltammeter limbs.

Hofmann voltameter is used for determining the chemical composition of water by volume, and the electrochemical equivalent of hydrogen by electrolysis of water. Consists of three vertical glass tubes connected to each other at the bottom, Stopcocks at the top ends of the outside tubes are closed while the inner cylinder is open at the top to allow the addition of water via a reservoir. Platinum electrodes mounted in rubber stoppers are used for the electrolysis of acidified water, for insertion in the open ends of the voltmeter limbs at bottom. Supplied with suitable metallic stand.

Hoffman's voltmeter to demonstrate that H2O consists of two volumes of hydrogen and one volume of oxygen with 50ml. graduated limbs with stopcocks,central limb with reserviour and remivable platinum electrodes.

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.
