Thumbnail Filmstrip of PTFE (Hydrophilic) Syringe Filters, 0.22um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk Images
Featuring a hydrophilic PTFE membrane with a 0.22um pore size, these 13mm syringe filters deliver rapid, efficient clarification of both aqueous and organic solutions. The surface-modified PTFE membrane wets out readily where unmodified PTFE would not, combining the broad chemical resistance of fluoropolymer media with the versatility needed for mixed aqueous and solvent samples. Each unit is housed in a transparent polypropylene body measuring 18mm in housing diameter, fitted with a Female Luer Lock inlet and Male Luer Slip outlet, and supplied nonsterile in packs of 500.
Key PTFE Membrane Characteristics
- Hydrophilic PTFE membrane that wets out for filtration of aqueous, organic, and alcohol-based solutions.
- High chemical resistance characteristic of fluoropolymer media, supporting use with aggressive solvents.
- 0.22um pore size for fine particulate removal during analytical sample preparation.
- Low protein binding behavior typical of PTFE media, helping preserve sample components.
- Effective filtration area of 0.76 cm² supports efficient throughput in a compact 13mm format.
Key Construction Characteristics
- Transparent polypropylene housing, ultrasonically welded and integrity tested to eliminate filter by-pass.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
- Housing diameter of 18mm with a holdup volume of less than 50 microliters to minimize sample loss.
- Maximum operating temperature of 90 degrees C and maximum operating pressure of 80 psi.
- Supplied nonsterile, 500 filters per pack, each labeled with membrane material and pore size.
The hydrophilic PTFE membrane maintains consistent flow and reliable retention across a wide range of solvents, while the low holdup volume protects costly or limited samples from unnecessary loss. The integrity-tested, welded housing provides dependable performance and helps safeguard sample integrity from preparation through analysis.
