Tisch SKU: SF04525NPS

Tisch Scientific Nylon Syringe Filters, 0.45 µm, 25 mm, 50/Pk - SF04525NPS

Tisch Scientific customer service specialists focus on laboratory products and can help source the right solution for specific applications. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. Nylon comes in sealed sterile packaging for cleanroom sample workflows while holding consistent retention across mixed-phase samples and draws aqueous buffers through without pre-wetting. Polypropylene construction maintains a low-dead-volume internal flow path while resisting degradation from routine sample matrices 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

• Alkaline-resistant across a broad range of aqueous buffers
• Absolute pore size rating provides consistent results across filtration protocols
• Low extractable contribution to sensitive analytical preparations
• Gamma-sterilized in sealed packaging for immediate aseptic use
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications

Housing Specifications

• Thermal-bonded construction keeps adhesives out of the fluid path
• Rigid polypropylene body holds its shape under manual filtration pressure
• Tough polypropylene body tolerates repeated handling at the bench
• 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.
