• PTFE (Polytetrafluoroethylene) is known for its chemical inertness, making it suitable for filtering a wide range of solutions, including those containing strong acids, bases, and various organic solvents. 
• It's particularly useful when other filter materials might degrade or leach contaminants into the sample. 
• Examples include filtration of aqueous and organic chromatography samples, buffers, and mobile phases. 

• In environmental analysis, PTFE syringe filters are used to filter samples containing complex matrices and aggressive chemicals.
• For biotechnology, their compatibility with biological samples and suitability for sterile processing makes them ideal for critical research applications. 

• PTFE syringe filters are widely used in sample preparation for HPLC analysis, ensuring that particles and impurities are removed before injection into the chromatographic system.
• They are often used in series, with a larger pore size filter (e.g., 0.45 µm) followed by a smaller pore size filter (e.g., 0.2 µm) to remove both larger particles and fine particulates. 

• PTFE is naturally hydrophobic, meaning it repels water. This property is beneficial in several ways:
  • It prevents the filter from becoming saturated with water when filtering aqueous solutions containing organic solvents.
  • It's useful in air and gas filtration applications where moisture can cause problems.
  • It allows for the filtration of organic solvents without the filter absorbing the solvent, ensuring efficient filtration. 

• Guarantees leak-proof sealing of the hose nipple and the holder without sealing rings
• Other connectors fit the holder onto reducing valves or pumps or onto pressure tanks
• Special polished surfaces allow easy cleaning and rinsing
• Sturdy stainless steel has a long lifecycle and is compatible with aggressive materials
• For use with 25mm membrane filters (20mm prefilter for liquid filtration)
• Sterilize by autoclave (max 134°C) or by dry heat (max 180°C)
• Weight; 170g

• HPLC and GC:PVDF syringe filters are well-suited for filtering samples before analysis by high-performance liquid chromatography (HPLC) and gas chromatography (GC) due to their low extractables and broad chemical compatibility. 
• General Analytical Applications:They are used to remove particulates from solutions before analysis, ensuring accurate and reliable results. 

• Sterilization and Clarification:PVDF filters are used to sterilize and clarify cell culture media, buffers, and other biological solutions. 
• Protein Solutions:They are frequently used for filtering protein solutions, enzyme preparations, DNA/RNA samples, and other biological fluids. 
• Low Protein Binding:PVDF membranes bind less protein than some other filter materials like nylon, making them ideal for applications where protein recovery is critical. 

• Syringe Filter made of SS-304 or SS-316 with chrome plated
• Lure spin fitting to attached manifold vent port easy
• Fine knurling for easy tightening

• Use for filter or cleaning small volumes of liquid as eyewash or photoresist.
• Purity virus solutions.
• Clarifying turbid solutions.
• For HAPLY applications and solvents.
