Electroplating Baths

Recommended for the purification and regeneration of electroplating baths.

  • High resistance to extreme pH conditions, as the papers are made from extremely pure cotton linters and cellulose, entirely without any additives.
  • Broad range of various papers with different filtration and retention times, according to individual needs.
  • Optimal filter papers for the analysis of electroplating baths are listed in the chapters “Ashless Filter Papers” and “Hardened Ashless Filter Papers”.
