HOFFMANN VOLTA METER 1626
See Chemistry Section. Cat. No. 6361.

ELECTROLYSIS CELL, OHP 1627
For use with an overhead projector to demonstrate the nature of chemical changes that occur with the electrolysis of aqueous solutions. Consists of a rectangular clear plastics container with two removable carbon electrodes, each fitted with 4mm sockets. A 6V, 0.03A M.E.S. lamp with flying leads and plug is fitted on the extension on one side of the cell. The cell can be divided by a separator that permits flow of the current but mechanically separates the products of electrolysis. Container size: 150 x50x55mm.
