LabExact PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10019

Gas and vent service calls for a hydrophobic syringe filter rated to the same sterilizing-grade pore size as its liquid counterpart. The PTFE matrix handles concentrated acids and bases across demanding methods and resists attack from the harshest process chemistries. The PP housing stays inert across common laboratory solvents and buffers in routine use while preserving sample chemistry across the flow path and holds its seal true run after run. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.

Membrane Characteristics

• Biological inertness resists enzymatic attack from proteases and lipases
• Surface energy near 18.5 dynes per centimeter repels oils and nonpolar liquids
• Low non-specific protein binding preserves recovery of biomolecules and therapeutic proteins during filtration
• Ionic and metallic extractable levels stay very low
• Gas-venting and liquid-blocking function survives repeated autoclave sterilization cycles

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Stable across the full aqueous pH range in routine sample work
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation

Particulates left in your organic solvents and reagents carry downstream into the step that depends on a clean feed. Reliable solvent prefiltration keeps a stray particulate from carrying into your downstream work before it carries into further processing.
