Types and Performance of Membranes Filter

A wide range of pore size and materials such as PTFE, PVDF, Nylon, PP, MCE are available, which gives customers more choices.

Nylon membrane filters are suitable for use with high PH samples; PES membranes filters are fit for filtration of compatible organic solvents and aqueous samples; PP membrane filters are widely used in analytical and research applications for the pharmaceutical, environmental, biotechnological, and agricultural industries; PVDF membranes filter are often used for purity during sterilization speed.

Performance of membranes filter

Different types of membranes filter provide diverse performance. In terms of thickness, PP is 160 to 230um, Nylon is 90 to 140um, PES is 110 to 140um, PVDF is 90 to 100um. As for maximum operating pressure, all of them are in 1.5 or 4.2 bar@23℃.

Compared chemical compatibility, PP is aqueous, and can act with mixed solvents; PES is used with strong bases, alcohols, protein, and peptides; Nylon is aqueous and fit for organic solvent and mixed solvent; PVDF is used with aggressive solvents, strong acids, alcohols, bases, and aromatics.
