PTFE (Polytetrafluoroethylene) Membrane Filters

Get PTFE filters for sterilizing air and gases, and filtering strong solvents in industrial applications.

PTFE Filter

Using polytetrafluoroethylene (PTFE) filters, pleated membrane cartridges work on the basis of surface filtration. Compared to depth-style filter cartridges, these cartridges provide up to a large filtration area due to their distinctive pleated design that increases the life span of the product.

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

In addition to having a uniform pore size, high porosity, thin texture, low resistance, and quick filtering speed, hydrophilic membranes readily absorb water. Strong acids, alkalis, and the majority of organic solutions are all perfectly filtered by them.

Hydrophobic PTFE Membrane Filters

Hydrophobic PTFE membrane filters are used in gas filtration. They can handle high temperatures (up to 260°C) & aggressive chemicals. These filters allow gas to pass through filter media & filter out the fluid.

Application of PTFE Membrane Filter

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

FAQS

What are the advantages of PTFE membrane filters?

Because PTFE membrane filters are strong, flexible, and chemical-resistant, they are perfect for filtering gases and air. extensively utilized in the chemical and pharmaceutical sectors.

What is the difference between hydrophilic and hydrophobic membrane filters?

Water flows to hydrophilic membrane filters that enable it to flow through while trapping oil. Hydrophobic properties membrane filters, on the other hand, are utilized to filter gasses and let loose, leaving moisture out, because they resist water.

What is the difference between depth filters and membrane filters?

Depth filters offer an extensive dirt-holding power and utilize materials like cellulose or activated carbon to gather particulates. Filters with membranes are ideal for accuracy filtering due to their clearly defined porous membrane that divides particles according to size.

What is the difference between PES and PTFE filters?

Since PTFE filters are ideal for gases and corrosive chemicals and repel water, PES filters attract water and operate effectively in solutions that involve water

Which pH range can be handled by a PTFE filter?

PTFE filters have high resistance to both basic and acidic substances as they can withstand a pH range of 0 - 14

What is ptfe filter?

Liquids and gases are capable of being filtered through PTFE membrane filters, that are created out of fluoropolymer material and are known for chemical composition and heat adaptability.
