Tisch Scientific Nylon Syringe Filters, 0.22 µm, 25 mm, 50/Pk - SF02225NPS

Tisch Scientific vets its filtration partners carefully, favoring those with a consistent record of dependable output. A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. The nylon matrix resists particle shedding through extended filtration cycles and ships pre-sterilized for aseptic sample preparation. The polypropylene housing preserves sample chemistry across the flow path while sustaining efficient flow on viscous samples and resists degradation from routine sample matrices. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Compatible with most HPLC mobile phases for sample clarification
• Non-fibrous membrane structure resists media shedding into the filtrate
• Amorphous-crystalline nylon blend composition doubles membrane burst strength over homopolymer nylon
• Resonance-stabilized amide bonds anchor nylon's resistance to alkaline hydrolysis
• Saturation moisture uptake reaches up to 8% by resin weight

Housing Characteristics

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Polypropylene housing withstands rated backpressure from dense sample matrices without deformation
• The seal formed against the membrane blocks bypass at rated operating pressure
• Rigid polypropylene body maintains its geometry through routine filtration pressure

Particulates in your buffers and mobile phases shorten column life and unsettle your baselines. Reliable particulate removal protects your instruments and your data across reagent, buffer, and mobile-phase preparation.
