Munktell regenerated cellulose membrane filters
Regenerated Cellulose Membrane filters are chemically resistant to almost all organic solvents and aqueous solutions in the pH range of 3 – 12.
Regenerated Cellulose Membranes have a low unspecific adsorption behaviour which makes them suitable for biological solutions. They are also recommended for filtering the mobile phase
during HPLC-examinations.
