Product Description

MS® PVDF membrane filter, particularly micro-porous membrane, can be prepared to exhibit high efficiency for particle removal. PVDF membrane has a low critical surface energy and conventional, hydrophobic, micro-porous PVDF membranes will not be wet by aqueous fluids. 
MS Membrane stack consists of reinforced-type PVDF membrane. It can ensure wet air and other gas pass through smoothly, even when the differential pressure is very low. It holds the opposite capability against PVDF hydrophilic membrane.
