PTFE Membrane Filters | Polytetrafluoroethylene Filter

Pleated membrane cartridges, utilizing polytetrafluoroethylene (PTFE) filters, operate on the principle of surface filtration. Thanks to their unique pleated design, these cartridges offer up to 8 times more filtration area compared to depth-style filter cartridges. The increased filtration area results in a longer service life.

PTFE filters offer high dirt holding capacity and are available in a range of porosities from 0.1 to 0.45 micrometres. They feature thermally bonded seams for leak-proof performance, and are reinforced with internal and external supports. Suitable for corrosive applications, these filters can be steam sterilized and validated with integrity testing methods.

Types of PTFE Membrane Filter

Hydrophilic PTFE Membrane Filters

Hydrophilic membranes easily absorb water and have a uniform pore size, high porosity, thin texture, low resistance, and fast filtration speed. They are ideal for filtering strong acids, alkalis, and most organic solutions.

Hydrophobic PTFE Membrane Filters

Hydrophobic membranes repel water and are mainly used for gas filtration. They can withstand high temperatures (up to 260°C) and harsh chemicals. Unlike hydrophilic filters, they allow air or gases to pass through but block liquids.

Application of PTFE Membrane Filter

Chemical Processing – Compatible with harsh chemicals in labs and industries.
Venting Applications – Prevents liquid entry while allowing gas flow in storage containers and fermentation.
Oil Filtration – Separates oil from water in industrial processes.
Aerosol Sampling – Ensures accurate air quality monitoring.
Biological & Protein Filtration – Used in life sciences for cell culture and protein purification.
Sterilization & Diagnostics – Ensures sterility in pharma and medical testing.

FAQS

What are the advantages of PTFE membrane filters?

PTFE membrane filters are durable, versatile, and chemically resistant, making them ideal for filtering air and gases. Widely used in chemistry and pharmaceuticals industries.

What is the difference between hydrophilic and hydrophobic membrane filters?

Hydrophilic membrane filters attract water, letting it through while repelling oils. On the other hand, hydrophobic membrane filters repel water and are used for filtering gases and venting, keeping moisture out.

What's the difference between depth filters and membrane filters?

Depth filters trap particles using materials like cellulose or activated carbon, offering high dirt-holding capacity. Membrane filters have a defined porous membrane that selectively separates particles by size, ideal for precise filtration.

What is the difference between PES and PTFE filters?

PES filters attract water and are good for water-based solutions, while PTFE filters repel water and are great for gases and corrosive chemicals

What pH range can a PTFE filter handle?

PTFE filters can withstand a pH range from 0 to 14, making them resistant to both acidic and basic solutions.
