Econe - Polyvinylidene Fluoride (PVDF) Filter Cartridge
A PVDF filter cartridge is a pleated membrane filter made from polyvinylidene fluoride (PVDF), a high-performance thermoplastic fluoropolymer. It is renowned for its broad chemical compatibility, mechanical strength, and thermal resistance. PVDF filter cartridges are widely used in liquid and gas filtration applications where aggressive media and high temperatures are involved.
- Excellent Chemical Resistance: PVDF filter cartridges provide outstanding resistance to acids, bases, solvents, and oxidants—ideal for harsh chemical environments.
- Hydrophilic & Hydrophobic Options: Suitable for both aqueous and non-aqueous fluid filtration in biotechnology, semiconductor, and chemical industries.
- High Flow & Low Pressure Drop: Pleated design with uniform pore structure ensures efficient throughput and minimal pressure loss.
- Thermal Stability: Operates at high temperatures up to 130°C, making it suitable for SIP and autoclave sterilization.
- FDA-Approved & ISO Certified: Made with FDA-compliant PVDF materials in ISO-class cleanrooms. Full traceability and testing documentation provided.
What is PVDF Filter Cartridge
These filters are available in both hydrophilic and hydrophobic variants, allowing them to be used for water-based or solvent-based solutions. PVDF’s low protein binding and extractables make it suitable for critical applications in pharmaceuticals, food & beverage, laboratory, and electronics manufacturing.
Unlike conventional filters, PVDF cartridges maintain excellent flow rates while offering long service life due to their pleated structure and robust media. They are compatible with most standard filter housings and are available in various lengths, micron ratings, and end cap configurations.
PVDF membrane filters are often chosen as final-stage filters in processes that demand high-purity, stability, and sterility. Their versatility, durability, and high efficiency make them a premium choice in demanding environments.
- Broad Chemical Compatibility: Resists acids, bases, oxidizers, and organic solvents. Ideal for harsh chemical filtration.
- Hydrophilic & Hydrophobic Options: Enables flexibility in filtering both aqueous and non-aqueous liquids or gases.
- High Temperature Resistance: Operates up to 130°C, suitable for steam sterilization and hot chemical processes.
- Low Extractables: Ensures ultra-pure filtration for sensitive applications like pharmaceuticals and electronics.
- Low Protein Binding: Prevents sample loss and ensures efficiency in biological and pharmaceutical processes.
- Pleated Structure: Maximizes filtration surface area for high flow rates and extended filter life.
- Sterilizable & Reusable: Can withstand multiple steam or gamma sterilization cycles.
- Standard Compatibility: Available in DOE, 222, 226 end caps and fits most common filter housings.
These features make PVDF pleated filter cartridges a highly reliable choice for demanding fluid or gas filtration processes.
PVDF filter cartridges are ideal for applications that demand chemical resistance, thermal stability, and filtration precision. Common industries and uses include:
- Pharmaceuticals: Filtration of solvents, injectables, and water-for-injection (WFI).
- Microelectronics: Final filtration of ultrapure water (UPW) and chemicals in semiconductor fabs.
- Chemical Processing: Resistant to aggressive acids and solvents in chemical manufacturing.
- Food & Beverage: Used in wine, beer, and syrup filtration where low extractables are required.
- Laboratories & Research: High-purity filtration of buffer solutions, DNA/RNA samples, and reagents.
- Medical Device Production: Sterile filtration in implantable and diagnostic product manufacturing.
