Hydrophobic

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Quality Control Testing - Optimized for delivering reproducible results by filtering contaminants in standard pharmaceutical protocols
• Biological Fluid Analysis - Protects sensitive downstream instruments from filtering contaminants that can cause system failure
