Re: [DIYbio] Re: Non-Platinum Electrophoresis Electrodes That Don't Degrade

I had an idea a few days ago about using platinum spark plugs as the electrodes. One could be placed at each end and the center used for the electrical in/outputs. I hope to be building a few boxes soon and would just thread holes for them. Another plus would be that they could be changed out easy if they ever corroded.

Any ideas?

I have been testing out a bunch of different metals and they either oxidize to death on the minutes timescale or in the case of stainless steel turn the buffer orange/brown.

Platinum wire is pretty expensive ~$1.00 cm^-1. Has anyone had luck with a cheaper metal at 100V or greater with TAE?

I have tried:

Nickel

Stainless Steel 430

Tinned Copper

Thinking of trying Titanium or Nickel Titanium (<= $4 meter^-1). Anyone ever tried these?

Thanks,
