Thumbnail Filmstrip of Hydrophilic PTFE Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Featuring a hydrophilic PTFE membrane with a 0.45um pore size, this 13mm syringe filter delivers fast, reliable clarification of aqueous and organic samples prior to instrumental analysis. The membrane is housed in a durable, chemically resistant polypropylene housing and configured with a Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) for secure syringe connection and easy sample dispensing. Each transparent unit is supplied nonsterile in packs of 100.
Key Hydrophilic PTFE Membrane Characteristics
- Hydrophilic PTFE wets readily with aqueous solutions, eliminating the need for prewetting required by standard hydrophobic PTFE.
- Broad chemical compatibility makes the membrane suitable for aggressive organic solvents, acids, and bases.
- 0.45um pore size provides effective particulate removal and sample clarification ahead of HPLC, GC, and other analytical methods.
- Low extractables help preserve sample integrity for sensitive detection.
- Low protein binding supports recovery of analytes in protein-containing samples.
Key Construction Characteristics
- Polypropylene housing offers broad chemical resistance and mechanical durability.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) ensure a secure, leak-resistant connection.
- Transparent housing allows visual monitoring of sample flow.
- Supplied nonsterile, 100 filters per pack.
- 13mm membrane diameter is suited to small sample volumes with reduced holdup.
This syringe filter maintains consistent flow and dependable particulate removal across a wide range of aqueous and organic samples. The combination of a hydrophilic PTFE membrane and robust polypropylene housing protects downstream instrumentation and helps deliver clean, reproducible results. The accurate, low-holdup design preserves sample integrity even with small or costly volumes.
