You can find chemical compatibility pages in the links section, i think in the tank construction folder. stainless steel doesn't work with HCl (cucl) but does work with the sulphuric acid variations. Dunno about the other etchants. ST

Not sure about ammonium persulphate, but ferric chloride definitely corrodes stainless steel. Leon -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

G'day Anthony & Leon Saw on eBay where a chap was selling magnetically coupled stainless steel centrifigal pumps. He said he was using one to pump Ammonium Persulphate. FeCl is corrosive to just about anything. I suspect it will even etch glass a little. Cheers Brian
