LabExact PTFE Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10193

A single-use hydrophobic vent filter reaches sterilizing-grade retention on a vent line without the autoclave cycle or in-line housing a reusable gas filtration setup would require. PTFE filters aggressive organic solvents without swelling or breakdown while resisting attack from the harshest process chemistries and repels water while passing gases and solvents freely. The polypropylene housing routes flow to minimize backpressure in service while standing firm against aqueous acids, bases, and alcohols during regular handling and delivers a chemically clean filtrate to the downstream step. A vent or gas line stays free of airborne bacteria once a hydrophobic, sterilizing-grade membrane is in the path.

Membrane Characteristics

• Non-wetting pore surface blocks liquid water while passing water vapor freely
• Gas-venting and liquid-blocking function survives repeated autoclave sterilization cycles
• Biological inertness resists enzymatic attack from proteases and lipases
• High membrane porosity, 70 to 80 percent void volume, delivers high flow at low pressure
• Validated against an aerosol Brevundimonas diminuta bacterial challenge

Housing Characteristics

• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Resists stress cracking from aqueous salt and buffer solutions
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening

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 so your downstream method starts with a clean sample.

Sterilization Guidance

Standard autoclave cycles at 121°C for 30 minutes prepare the device for sterile workflows.
