This is the simple ordinary 4-port cell usually for corrosion study.
Salt bridge and gas inlet/outlet pipe come with the cell.
Rubber stoppers are used to stabilize the electrodes.
The matching electrodes with this cells are usually:
Reference electrode: CS900 Saturated Calomel electrode
Counter Electrode: CS910 Pt conductivity electrode or CS911 Pt plate electrode
Working electrode: CS921 metal working electrode or CS946 Specimen holder with your sample assembled
