Membrane Types

Membrane solutions  provides the most popular type of membranes to cover a very wide range of applications. The main selection criteria are solvent-compatibility and porosity.

• PTFE membranes are compatible with almost all solvents, acids and bases.
• Nylon 66 membranes are compatible with most solvents, organic and aqueous; but use with strong acids, methylene chloride and DMF is not recommended.
• Cellulose nitrate is primarily used for pre-filters and is compatible with many but not all aqueous or non-aqueous solvents.
• Cellulose acetate membranes are not compatible with organic solvents. They are well suited for aqueous solutions and are specially recommended for proteins and protein-related samples.
