Description
Polyvinylidene Fluoride Membrane Filters are high-performance filtration materials designed for demanding applications requiring exceptional chemical resistance, heat tolerance, and mechanical strength. These filters provide reliable and efficient filtration, particularly suited for scenarios involving harsh solvents and high-temperature conditions.
Key Features:
- Superior Chemical Compatibility: Resistant to various organic and inorganic solvents, including strong acids, aliphatics, aromatics, alcohols, aldehydes, ketones, ethers, and more.
- High Heat Resistance: Can withstand high-pressure steam sterilization at temperatures ranging from 128-142°C, ensuring reliable performance during sterilization procedures.
- Low Protein Binding: The membrane’s structure offers minimal protein adsorption, making it ideal for biological filtration and applications where protein recovery is critical.
- Hydrophobic Nature: Naturally hydrophobic, suitable for filtering air, gases, and solvents. Hydrophilic treatment allows for effective liquid filtration as well.
- Excellent Mechanical Strength: Manufactured with a uniform pore structure, providing flexibility and robustness, preventing membrane breakage during filtration.
- Manufactured in Clean Rooms: Production under cleanroom conditions ensures the absence of impurities, preserving sample integrity.
Recommended Applications:
- HPLC Sample Preparation: Efficiently prepares samples for high-precision chromatographic analysis.
- Biological Sample Filtration: Low protein-binding properties are ideal for filtering biological samples, ensuring maximum recovery.
- Air Filtration and Degassing: Reliable for purifying air and removing particulates from gases.
- General Filtration: Suitable for a wide range of laboratory and industrial filtration processes.
- Liquid Sterilization & Particle Removal: Effective for filtering solutions during sterilization and clarification procedures.
