Don't go for commercial cells and holders.It is damn expensive and not really worth it. Use Nylon cap ( using a rod of appropriate diameter) with the electrode fitting holes for the RE,WE and CE. You can get it done in the workshop or some where outside where a lathe is available.

Thanks Dr. Lakshminarayanan!
