Dimethyl sulfoxide

DMSO from MicroChemicals

In addition to our solvents acetone and isopropyl alcohol, we are now offering our new MicroChemicals DMSO in ULSI quality. The solvent and stripper is available in 2.5 L containers and can be ordered as single bottles or in the packaging unit of 4 x 2.5 L.

Due to its low vapor pressure and its water solubility, DMSO is an excellent stripper for resists respectively Lift-off media and is a non-toxic substitute for the NMP, which has been classified as toxic since a while. The optional addition of cyclopentanone or MEK increases the performance of the stripper for certain
applications and significantly lowers the melting point of pure DMSO.

If you are interested in a sample of our DMSO, please let us know.
