Lever handle is spring loaded and has locking arrangement to ensure that rotation does not go beyond 90°, standard nozzles have 1 mm bore, inlet 1/4 in. BSP, flange diam. 54 mm with three holes to screw on bench or any other surface. Designed to operate pressure upto 2 p.s.i (0.14 Kg/cm2), suitable for coal gas, natural gas or bottled L.P.G., supplied complete with adaptor.

With folded edges.

The glass unit has two connected limbs, each graduated 50 x 0.2 ml, with stopcocks, with a tube and a funnel shaped reservoir bulb.

To demonstrate water decomposition by electrolysis and with applications in the evaluation of the electro chemical equivalent of hydrogen. For electrolysis of water, platinum electrodes are used; For electrolysis of ammonia or hydrochloric acid, Carbon electrodes are used. The electrodes are mounted in rubber stoppers for insertion into open ends of voltameter limbs. The glass unit has two connected limbs capacity 50 ml, Integral with reservoir tube and funnel shaped bulb, with a stop clock at the top of each limb. Electrodes available seperately.
