Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - SF14505

Tisch Scientific welcomes bulk and blanket orders with volume discounts. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The PES membrane draws aqueous buffers through without pre-wetting while preserving dilute proteins and analytes in the filtrate and tolerates aqueous buffers, aliphatic alcohols, and glycols. The PP housing keeps the fluid path low in extractable contamination while preventing sample bypass under rated operating pressure and maintains a low-dead-volume internal flow path. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

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

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Thermal-bonded construction keeps adhesives out of the fluid path
• Resists aqueous acids, bases, and alcohols in routine sample prep

Filtering particulates upstream protects the column investment your methods depend on. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.
