Tisch Scientific Polyethersulfone (PES) Syringe Filters, 1 µm, 25 mm, 100/Pk - SPEC18102

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. PES holds consistent absolute retention at the rated pore size and tolerates aqueous buffers, aliphatic alcohols, and glycols. The PP housing prevents sample bypass under rated operating pressure while contributing minimal extractables to the filtrate and routes flow to minimize backpressure in service. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Absolute pore size rating gives consistent results across protocols
• Stable across the full pH 1 to 14 operating range
• High flow rate with low extractable background for clean preparations
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases
• Low protein binding preserves dilute analytes for maximum recovery

Housing Specifications

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Stable across the full aqueous pH range in routine sample work

Sample clarification before injection is the cheapest insurance your chromatography system has. Pre-injection filtration protects the resolution your methods depend on across your chromatography methods.

• Prefiltration Protection - Removes larger particles before fine filtration, extending 0.22µm membrane service life and reducing operational costs
• Clinical Sample Processing - Clarifies serum, plasma, and biological fluids containing cellular debris before immunoassay or diagnostic analysis
• Fermentation Broth Clarification - Efficiently separates microbial cells and protein aggregates from valuable metabolite solutions in bioprocessing
• Mobile Phase Prefiltration - Protects HPLC columns and system components from particulates in freshly prepared aqueous and organic solvents
• Viscous Sample Preparation - Processes high-viscosity samples and suspensions that challenge finer membranes, enabling downstream analysis
• Environmental Water Analysis - Removes suspended sediments and particulates from surface water samples before microbial or chemical testing
