Hoffmann’s Apparatus – Glass Parts (Mini)
For qualitative and quantitative study of the electrolytic decomposition of electrolytes such as water, hydrochloric acid etc.. Consists of two vertical 50mL, gas-collecting, graduated glass burets with stopcocks at top and joined by a bridging tube to a reservoir and fitted with a pair of platinum electrodes at the bottom ends. A lead wire connecting the platinum electrode passes through the glass tube for external connections, so that only the platinum electrode comes in contact with electrolyte. Packed in a styrofoam case. Mounted on a cast iron stand designed for safe clamping. Requires a 6V battery or low voltage D.C. power supply for operation (not supplied).
