Description

PVDF (Polyvinylidene Fluoride) membrane filters are naturally hydrophobic membranes designed for solvent filtration, gas filtration, and analytical sample preparation.

They are widely used in HPLC sample filtration, microbiology gas filtration, and chemical solvent processing due to their excellent chemical resistance and low extractables.

What is a PVDF Membrane Filter?

PVDF membrane filters are made from polyvinylidene fluoride, a high-performance fluoropolymer material with strong chemical resistance and thermal stability.

Unlike hydrophilic membranes such as PES or CA, PVDF membranes are naturally hydrophobic, making them ideal for:

organic solvent filtration
gas filtration
sample preparation in analytical chemistry
HPLC mobile phase filtration

Hydrophobic Nature of PVDF Membranes

PVDF membranes are inherently hydrophobic, meaning they repel water and are best suited for non-aqueous applications.

Key properties:

Naturally hydrophobic (no surface treatment required)
Excellent compatibility with organic solvents
Requires pre-wetting for aqueous filtration (if used)

Applications of PVDF Membrane Filters

HPLC sample preparation
Solvent filtration (organic phase)
Gas sterilization filtration
Protein & enzyme analysis
Analytical chemistry laboratories
Environmental testing
Pharmaceutical QC

How to Choose PVDF Membrane Filter

By pore size:

22 μm –Sterile filtration, fine particles
45 μm –HPLC & general lab use
65–5.0 μm –prefiltration

By diameter:

13–25 mm –syringe filters
47 mm –standard lab filtration
90–293 mm –industrial filtration

Frequently Asked Questions

Is PVDF membrane hydrophobic?

Yes. PVDF membranes are naturally hydrophobic and ideal for solvent and gas filtration applications.

Can PVDF membrane filter water?

Not directly. PVDF is hydrophobic and requires pre-wetting agents if used for aqueous filtration.

What is PVDF membrane used for?

It is widely used for HPLC sample preparation, solvent filtration, and gas filtration.

PVDF vs PTFE membrane, what is the difference?

PVDF has higher flow rate and moderate chemical resistance, while PTFE has stronger chemical resistance but lower flow performance.

Is PVDF suitable for protein filtration?

Yes, PVDF has moderate protein binding and is used in biochemical applications.
