Generic A Series Hydrophilic PVDF Membrane Filters for Solvent Filtration and HPLC Sample Preparation (PVDF-HA3µm, Φ47mm_50pcs/Box)

DiffuLayer A Series Hydrophilic PVDF membrane filters are developed from hydrophobic PVDF membranes through advanced hydrophilic modification. This process significantly reduces the contact angle, greatly improving wettability and water flow rates. With extremely low protein binding, broad chemical compatibility, and high filtration efficiency, these membranes are widely used in culture media preparation, protein solution clarification, and various biological sample treatments.

• Excellent chemical compatibility: Stable with most organic solvents (aliphatic hydrocarbons, aromatic hydrocarbons, alcohols, aldehydes, etc.), with minimal extractables.
• Ultra-low protein binding: Significantly lower than MCE, Nylon, and PTFE membranes, ensuring minimal sample loss.
• High filtration rate: Hydrophilic modification enables rapid filtration of aqueous solutions with lower pressure requirements.
• Outstanding thermal and oxidative resistance: High mechanical strength, suitable for demanding conditions without rupture.
• Multiple sterilization methods: Compatible with autoclaving, ethylene oxide, and gamma irradiation.
• Batch-to-batch consistency: Reliable and reproducible performance for critical experiments.
• Clarification and sterile filtration of culture media and protein solutions
• Sterile filtration of antibiotics, ethanol, and other liquids
• Biological sample preparation (e.g., receptor binding assays, TCA precipitation)
• Solvent filtration and HPLC sample preparation
