0.22 μm 47mm hydrophilic PVDF membrane filter discs are engineered for biomedical research applications requiring high-purity filtration. These premium filters ensure contaminant-free solvents and mobile phases for accurate mass spectrometric analysis.

• Modified hydrophilic surface for enhanced filtration performance
• High flow rates and throughput for efficient sample processing
• Excellent temperature resistance for demanding experimental conditions
• Very low protein binding to maximize sample recovery
• Broad chemical compatibility with various solvents and solutions
• Low extractables ensuring sample purity
• Superior mechanical properties for reliable operation
• Manufactured in 100,000 grade cleanrooms for consistent quality

Use 0.22μm pore size filters for complete bacterial retention and sterilization applications. These filters effectively remove biological contaminants while maintaining sample integrity.

For applications requiring retention of larger biological contaminants, 0.45μm or larger pore sizes are recommended. These support microorganism growth for subsequent culture and analysis.

Our experienced technical team provides comprehensive support including product selection guidance, operational optimization, and troubleshooting assistance. Services include remote diagnostics, telephone/email support, and on-site visits when required.

Each membrane filter disc is individually packaged in polyester bags or cases with clear labeling. Multiple packs are securely sealed in protective cartons with air cushioning to ensure safe delivery via ground, air, or water transport.
