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.
