Thumbnail Filmstrip of PTFE (Hydrophilic) Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Featuring a hydrophilic polytetrafluoroethylene (PTFE) membrane with a 0.45um pore size, this 25mm syringe filter delivers fast clarification of both aqueous and organic samples without the prewetting step required by standard PTFE. The membrane is housed in a transparent polypropylene body and is supplied nonsterile in a pack of 100. A Female Luer Lock inlet and Male Luer Slip outlet provide a secure syringe connection and easy dispensing into downstream vessels.
Key PTFE (Hydrophilic) Membrane Characteristics
- Hydrophilic PTFE wets out spontaneously, allowing direct filtration of aqueous solutions, buffers, and water-miscible solvents.
- Broad chemical compatibility makes the membrane well suited to aggressive organic solvents and acids.
- The 0.45um pore size removes fine particulates to clarify samples and protect downstream instrumentation.
- Low extractables support clean, reproducible results in analytical workflows.
Key Construction Characteristics
- Transparent polypropylene housing provides chemical resistance and lets users see the sample during filtration.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection for secure attachment and controlled dispensing.
- 25mm membrane diameter sized for moderate sample volumes.
- Supplied nonsterile, 100 filters per pack.
This filter maintains sample integrity by removing particulates while withstanding a wide range of solvents and reagents. The hydrophilic PTFE construction provides consistent, reproducible flow for analytical sample preparation, helping protect HPLC and GC systems from particulate contamination.
