Tisch Scientific PTFE Syringe Filters, 0.22 µm, 25 mm, 100/Pk - SF14468

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The hydrophobic PTFE membrane provides bacterial retention in gas and vent streams while resisting attack from the harshest process chemistries and repels water while passing gases and solvents freely. The PP housing keeps the fluid path low in extractable contamination while holding a reliable seal against the membrane edge and stays inert across common laboratory solvents. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Stable across a wide operating temperature range for demanding methods
• Absolute pore size rating gives consistent results across protocols
• Sterilizing-grade gas and vent filtration at sub-micron pore sizes
• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Filters aggressive organic solvents without swelling or breakdown

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Optimized internal geometry minimizes backpressure in service
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Medical-grade polypropylene with broad chemical compatibility

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on so your filter holds its integrity through the run. Contact Tisch Scientific for technical guidance on selecting the right filtration product for your specific application requirements.

• Aggressive Solvent Sterilization - Provides sterile filtration of DMF, DMSO, THF, and chloroform while maintaining chemical purity
• Sterile Filtration Applications - Removes bacteria completely from non-aqueous pharmaceutical preparations requiring microbiological control
• HPLC Sample Preparation - Protects chromatography columns from particulates and bacterial contamination in organic mobile phases
• Strong Acid Sterilization - Safely sterilizes concentrated HCl, H2SO4, and HNO3 solutions without membrane degradation or contamination
• Air and Gas Venting - Hydrophobic barrier provides sterile gas passage while blocking liquid intrusion in pressure systems
• Protein Precipitation Clarification - Sterilizes samples after TCA or organic solvent precipitation in analytical workflows
