PES Syringe Filters, 5.0um, 25mm, Double Luer Lock, PP Housing, Sterile, 100/Pk
Tisch SKU: SPEC18108

Tisch Scientific Polyethersulfone (PES) Syringe Filters, 5 µm, 25 mm, 100/Pk - SPEC18108

Tisch Scientific keeps ordering simple, turning quotes and questions around quickly. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Naturally hydrophilic PES wets on contact with aqueous samples and tolerates aqueous buffers, aliphatic alcohols, and glycols. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use while maintaining a low-dead-volume internal flow path and contributes minimal extractables to the filtrate. When sterile or particle-free preparation matters at the bench, the syringe filter delivers it with minimal added handling.

Technical Specifications

• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• High flow rate with low extractable background for clean preparations
• Stable across the full pH 1 to 14 operating range
• Low protein binding preserves dilute analytes for maximum recovery
• Broad compatibility with aqueous buffers, aliphatic alcohols, glycols, and strong bases

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.

• Cell Harvest Clarification - Clarifies harvest samples containing cell debris before fine filtration while preserving proteins via low binding
• Downstream Filter Protection - Removes coarse contaminants using a sterile device to significantly extend the life of downstream fine filters
• Serum Prefiltration - Removes aggregates and precipitates from serum samples before sterile filtration while preserving proteins via low binding
• Biological Buffer Clarification - Rapidly clears visible particles from laboratory buffers to protect analytical equipment and prevent clogging
• Environmental Sample Prep - Clarifies turbid water samples containing suspended solids to prepare them for microbiological analysis workflows
• Protein Solution Prefiltration - Gentle prefiltration removes large protein aggregates while preserving native structure via the PES membrane
