Featuring a naturally hydrophilic polyvinylidene fluoride (PVDF) membrane rated at 0.22um, these ultrasonically welded syringe filters deliver fast, efficient clarification and sterile filtration of aqueous and organic solutions. The 13mm membrane sits within an 18mm transparent acrylic housing that bidirectionally supports the membrane, while a low holdup volume of less than 50 microliters helps preserve small or costly samples. Each unit is supplied sterile in individual packaging and labeled with the specific membrane material and pore size for easy identification.
Key PVDF Membrane Characteristics
- Hydrophilic PVDF membrane wets readily for filtration of aqueous and organic samples.
- Very low protein binding helps maximize recovery of valuable analytes.
- Low extractables support clean, interference-free downstream analysis.
- Broad chemical compatibility, including aggressive acids and alcohols.
- 0.22um rating provides sterilizing-grade retention and protects analytical columns.
Key Construction Characteristics
- Transparent acrylic housing, ultrasonically welded to eliminate filter bypass.
- Female Luer Lock inlet with Male Luer Slip outlet (Luer-Lok/Luer Slip) for broad device compatibility.
- Effective filtration area of 0.76 cm squared with a holdup volume under 50 microliters.
- Maximum operating temperature of 50 degrees C (122 degrees F) and maximum operating pressure of 80 psi.
- Supplied sterile, 50 filters per pack.
This filter maintains sample integrity through integrity-tested, welded construction that prevents particulate bypass and ensures consistent retention. The combination of low protein binding, low extractables, and broad chemical compatibility provides reliable, reproducible results across demanding sterile filtration and chromatography workflows.
