Tisch Scientific Nylon Syringe Filters, 0.45 µm, 4 mm, 200/Pk - SF17503

Tisch Scientific backs every order with friendly, knowledgeable support for questions and quotes. Syringe filters give the analyst a single-use device for clarifying samples right at the bench. The nylon membrane comes in a non-sterile format for routine analytical preparation while resisting alkaline buffer systems and resists particle shedding through extended cycles. Polypropylene construction maintains a low-dead-volume internal flow path while contributing minimal extractables to the filtrate and holds a reliable seal against the membrane edge. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Stable across the pH 3 to 12 operating range
• Non-sterile for routine clarification and sample prep
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Low extractable contribution to sensitive analytical preparations
• High tensile strength for stability under elevated differential pressures

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Thermal-bonded construction keeps adhesives out of the fluid path
• Low extractable contribution protects sensitive downstream analyses

Reproducible separations start with samples that reach the column free of particulates. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.
