Thumbnail Filmstrip of PTFE Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Nonsterile, Transparent, 100/Pk Images
Featuring a hydrophobic polytetrafluoroethylene (PTFE) membrane with a 0.45um pore size, this 13mm syringe filter delivers fast, efficient clarification of organic solvents, aggressive chemicals, and gases. The 13mm membrane is welded into an 18mm transparent polypropylene housing with a 0.76 cm2 effective filtration area, providing a low holdup volume of less than 50 microliters to minimize sample loss. Female Luer-Lok inlet and male Luer slip outlet connections ensure a secure fit to standard syringes, and each device ships nonsterile in packs of 100.
Key PTFE Membrane Characteristics
- Naturally hydrophobic membrane ideal for filtering organic solvents, acids, bases, oxidants, and gases
- Broad chemical compatibility across a wide range of aggressive and nonaqueous samples
- 0.45um pore size targets particulate removal and sample clarification
- Suited to sterile venting and process air or gas filtration where a hydrophobic barrier is required
- Ultrasonically welded construction eliminates adhesives that could leach into the sample
Key Construction Characteristics
- Transparent polypropylene housing with an 18mm outer diameter and 13mm membrane
- Female Luer-Lok inlet and male Luer slip outlet for secure syringe attachment
- Effective filtration area of 0.76 cm2 with a holdup volume under 50 microliters
- Withstands a maximum operating temperature of 90 degrees C and a maximum operating pressure of 80 psi
- Supplied nonsterile, 100 filters per pack
This filter maintains sample integrity through low holdup volume and an integrity-tested weld that helps prevent filter bypass. The chemically resistant PTFE membrane provides reliable, repeatable performance across demanding solvent and gas applications. Each filter is labeled with its membrane material and pore size for easy identification outside its original packaging.
