Solvent Cleans

  • Acetone, IPA
    • Solvent for organics, IPA cleans remaining residues due to acetone's high evaporation rate
  • Acetone, Methanol
    • Similar to above except Methanol is more toxic, and a polar chemical versus IPA which is non-polar
  • Acetone, Methanol, IPA
  • Acetone, Methanol, IPA, DI Water
  • Remover PG (50°C), IPA
  • Dichloromethane, IPA
    • Caution, high evaporation rate may leave residue and beakers get quickly condense water/ice
  • Nanostrip?
