Main Applications Of Hydrophobic And Hydrophilic PTFE Membrane Filter

Hawach is a professional technology membrane manufacturer integrating analytical chemical product development, manufacturing, sales, and service. Since its establishment, the company has maintained a high speed and steady pace of development, along with scientific and technological innovation, to provide customers with more valuable products of the core concept.

PTFE material, hydrophobic and hydrophilic two forms, strong chemical corrosion resistance, good heat resistance, compared with other filtering materials, with a larger flow rate, very low protein adsorption, and temperature resistance.

PTFE hydrophobic membranes become PTFE hydrophilic membranes after treatment with ethanol or isopropanol. The hydrophobic filter cannot be wetted naturally, and hydrophilic membranes can be wetted naturally. Suitable for filtering microorganisms, steam, and all kinds of corrosive liquid.

Hydrophobic PTFE membrane filter

Hydrophobic PTFE membrane, good hydrophobicity, and strong temperature tolerance. The surface filter membrane is a hydrophobic filter with no support. It can be used under extreme chemical or temperature conditions (up to 260°C) that other membranes cannot withstand. Hydrophobic PTFE membrane filter can be used for atmospheric filtration detection, usually only for air filtration. Uncommon hydrophobic membranes can also be used to filter certain organic solvents, such as ethanol. In actual use, liquids that can pass hydrophobic filtration can also pass hydrophilic filtration. Therefore, it is recommended to use hydrophilic filtrate.

Hydrophilic PTFE membrane filter

Hydrophilic PTFE membrane filter can be used to filter aqueous solutions, most organic solutions, strong acid, and alkali solutions, and can be used as experimental sewage clarification filtration, etc.

Features and advantages of PTFE membrane filter

1. No fiber, no leachable problem
2. High durability and fast filtering speed
3. Low background value, accurate test results
4. High temperature resistant and sterilizable
5. Resistance to strong acids, strong alkalis, and corrosive solutions
6. Wide chemical compatibility, can withstand the filtration of organic solvents such as DMSO, THF, dichloroalkane

Application of PTFE membrane filter

Hydrophobic PTFE membrane filter is mainly used in:

1. Air monitoring and gas filtration
2. With strong chemical compatibility, almost competent for all organic solvents and strong corrosion chemicals filtration
3. In the filtration of aqueous phase solution must first use ethanol or isopropyl alcohol pre-infiltration, aqueous phase solution can be filtered

Hydrophilic PTFE membrane filter is mainly used in:

1. Analysis of water samples to isolate RNA
2. Clarifies filtered acid, alkali, and cryogenic liquids and diluted protein solutions
3. Filtration of mixtures suitable for HPLC mobile phase and other water systems and organic solvents
