I use this very often to filter protein samples dissolved in hexafluoroisopropanol.
Filtering protein samples before mass-spec analysis
N/A
Easy to use
This membrane is compatible with hexafluoroisopropanol.
Compatible with the solvent that I use often for sample prep
A bit expensive
If you are using hydrophobic solvent, and you have to filter the sample, I highly recommend this.
