10.
Again, grab the plunger/sleeve assembly and support the plunger with your fingert ip.
Then push the cell base (with the anode and separator located inside) over the assembly,
press onto the plunger, and turn the cell into the upright position.

Attach the cell lid, insert the cell into the bracket, and tighten the wing nut.
3 Disassembly and Cleaning
After use, disassemble the test cell in the reverse order of assembly. Dispose electrodes and
electrolyte properly. Clean wetted cell parts with deionized water and/or other appropriate
detergent wash and solvent. PEEK sleeve, cell base and plunger may be additionally cleaned in
an ultrasonic bath. After cleaning with water, dry parts with compressed air. Before building a
new cell, dry parts overnight at 80°C under vacuum. This treatment is essential for the PEEK
sleeve, as the PEEK polymer may absorb water.
Cell base and plunger may be additionally treated with aqueous nitric acid (20%, 2 hours at
room temperature). Do not apply this treatment to any other cell parts.
Notes:
Protect yourself against chemical hazards. Electrolyte may spill out during cleaning.
Electrode materials and electrolyte may react with ambient atmosphere or solvents used
for cleaning. Wear appropriate protection equipment, goggles and gloves.
Clean all cell parts right after disassembly. Leaving cell parts in contact with ambient
atmosphere while still being wetted with electrolyte may result in severe corrosion.
Sleeve removing tool
The sleeve can be easily removed with the sleeve removing tool. First detach the PTFE Plug
assembly, then position the tool beneath the rim of the sleeve and lift it out of the cell base.
NOTE:
Leaving cell parts in contact with ambient atmosphere while still being wetted with
electrolyte may result in severe corrosion.
