0.1~5.0 Micron PTFE Microporous Filter Membrane

0.1~5.0 Micron PTFE Microporous Filter Membrane

Introduction:

PTFE (Polytetrafluoroethylene) microporous filter membrane is made of expanded polytetrafluoroethylene and has excellent chemical compatibility. Modified to become a hydrophilic membrane, it is widely used in aqueous and organic solutions.

Parameters:

Optional diameter: 13mm-800mm

Optional pore size: 0.1um/0.22um/0.45um/1.0um/x5.0um, etc.

Alias: Hydrophilic Polytetrafluoroethylene, English code PTFE.

Chemical formula: -(CF2CF2)n-

Thickness: 16±1 (filament)

Melting point: 327±10°C

Thermal decomposition temperature: 415°C

Burning temperature: Non-flammable

Density: 2.17-2.23g/cm3

Chemical stability: Polytetrafluoroethylene can withstand almost all chemical reactions except melting alkali metals, chlorine trifluoride, chlorine pentafluoride, and liquid fluorine.

Features and Benefits:

1. Extremely strong chemical corrosion resistance and good heat resistance.
2. Larger flow rate, extremely low protein adsorption, and temperature resistance.
3. Suitable for filtering microorganisms, steam, and various corrosive liquids.
4. Suitable for all solvents, acids, and salts, with no soluble substances.
5. Disinfectant filtration is more suitable than other materials. Good pore size consistency.

Application Fields:

HPLC mobile phase and other mixtures of water and organic solvents; analysis of water samples, separation of RNA, filtration of most organic solvents, strong acids and alkalis, widely used in pharmaceuticals, biochemistry, microelectronics, and laboratories, etc.

Selection reference for filter membranes: (Specifically depends on chemical compatibility)

1. For hydrophilic samples suitable for filtering water-based solutions, choose hydrophilic membrane discs. Available membrane discs include: CN-CA (water membrane), PES membrane, nylon membrane, PP membrane, etc.
2. For highly corrosive organic solvents: choose membranes such as PTFE.
3. For protein solutions, choose membranes with low protein adsorption, such as CN-CA, PES, PTFE, and PVDF hydrophilic membranes.
4. For ion chromatography: generally choose PES filter membranes.
5. For gas and steam filtration, choose hydrophobic membranes such as PTFE or PVDF.
6. For high-temperature liquids, choose PES filter membranes, PVDF hydrophilic, or PTFE hydrophilic membranes.
