Overview

The AELAB PVDF Membrane Filter is a high-performance filtration solution offering excellent chemical compatibility, low extractables, and superior flow rates. Available in both hydrophilic and hydrophobic versions, PVDF membranes are ideal for protein binding, sample preparation, sterilization, and air/gas filtration. With pore sizes from ultrafine to general clarification, they deliver reliability across pharmaceutical, biotechnology, and analytical laboratories.

🔬 How It Works?

PVDF membranes utilize a microporous fluoropolymer structure that allows efficient filtration of liquids and gases. Hydrophilic PVDF membranes are ideal for aqueous sample clarification and sterilization, while hydrophobic PVDF versions excel in air monitoring, gas sterilization, and vent filtration. The material’s high protein binding also makes it suitable for protein immobilization and analysis.

💡 Advantages

• Broad chemical compatibility for aggressive solvents
• Low extractables, ensuring accurate analytical results
• High protein binding – suitable for protein assays and binding studies
• Hydrophilic option for aqueous solutions, hydrophobic option for air/gas applications
• Superior flow rates reduce processing time

🔍 Recommended Models by Use Case

• Hydrophilic 0.22μm PVDF membranes → Sterilizing filtration of culture media and biological samples
• Hydrophilic 0.45μm PVDF membranes → General aqueous clarification and HPLC sample preparation
• Hydrophobic PVDF membranes → Gas sterilization, air monitoring, and vent filters for fermenters and containers

🧪 Ideal For

• Pharmaceutical and biotechnology labs
• Protein binding and immobilization studies
• Chromatography sample preparation (HPLC, GC)
• Sterilization of aqueous solutions and solvents
• Air monitoring and sterile gas filtration
• Food, beverage, and environmental testing
