Electrochemistry workplace<br />
Scope of delivery<br />
2 Cell batteries made of chemical-resistant<br />
plastic. They can easily be unscrewed and<br />
disassembled for cleaning. Filter paper is<br />
used as the membrane between the cells.<br />
Four galvanic cells can be set up simultaneously<br />
18 Plate electrodes (28 x 43 mm) which fit into<br />
the cell compartments described above,<br />
made of seven different materials: Cu<br />
(4 electrodes), Zn (4), Fe (2), Ag (3), C (graphite,<br />
2), Pt (mesh electrode, 1), Ni (mesh<br />
electrode, 2).<br />
2 Plastic plates and Mg tape for making Mg<br />
electrodes.<br />
3 Storage containers for electrodes which<br />
must be kept submerged in liquid during<br />
storage.<br />
1 Abrasive stone for cleaning the electrodes.<br />
1 Set of paper diaphragms (100 sheets).<br />
4 Droppers with rubber bulbs.<br />
1 Manual (> 668 421)<br />
Additionally recommended:<br />

Instructor's manual<br />
“Introduction to Electrochemistry“<br />
112 pages, A4 size, in German.<br />
Instructor's manual for a complete course in<br />
electrochemistry, designed for advanced<br />
secondary education. It contains all the theoretical<br />
background and evaluations of the 17<br />
experiments which can be conducted with the<br />
electrochemistry work place.<br />

Measuring unit for electrochemistry workplace<br />
The measuring unit is inserted in the compartment<br />
of the workplace provided for that purpose<br />
to enable mesurement. The measuring unit<br />
can also be used independently of the electrochemistry<br />
workplace.<br />
Scope of delivery<br />
1 Measuring instrument for virtually currentless<br />
voltage measurement from 1 mV to 10<br />
V, switchable in 7 measuring ranges<br />
Internal resistance approx. 10 8 Ω<br />
1 Motor with disk as current indicator<br />
(max. 3 V), for demonstrating flow of current<br />
in fuel cells<br />
4 Connecting leads with croc-clips<br />
1 Plug-in supply unit for connection to 230 V<br />
