Glass microfiber (GMF) membranes

Glass microfiber is hydrophilic and has excellent compatibility with organic solvents and strong acids (except hydrofluoric acid) and bases. However, it is not a micropore membrane and so has a slightly less exact retention efficiency than polymeric membranes. GMF can also contribute extractables that interfere with ionic and metals analysis.

Looking for a filter paper, membrane filter, or syringe filter Let Cytiva help youÂ find the optimal filterÂ for your needs to ensure reliable analysis.
