Thumbnail Filmstrip of PTFE (Hydrophilic) Syringe Filters, 0.22um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Featuring a naturally hydrophilic polytetrafluoroethylene (PTFE) membrane with a 0.22um pore size, these 13mm syringe filters deliver fast, efficient clarification of aqueous, organic, and alcohol-based solutions. The membrane is housed in a transparent polypropylene body with an 18mm housing diameter and ultrasonically welded construction that eliminates filter bypass. Female Luer Lock inlet and Male Luer Slip outlet fittings allow either sample injection or aspiration, and each filter is supplied nonsterile in a pack of 100.
Key PTFE Membrane Characteristics
- Hydrophilic PTFE membrane wets readily with both aqueous and organic solvents, removing the need for prewetting.
- 0.22um pore size provides fine clarification and particulate removal from prepared samples.
- Broad chemical compatibility supports filtration of aggressive solvents and reagents.
- Low protein binding and low extractables help preserve sample integrity for downstream analysis.
- Integrity tested to ensure a proper filter fit and weld for reliable, consistent performance.
Key Construction Characteristics
- Transparent polypropylene housing with a 13mm membrane diameter and 18mm housing diameter.
- Female Luer Lock inlet and Male Luer Slip outlet for flexible syringe connection.
- Ultrasonically welded housing with low hold-up volume for better handling of small sample volumes.
- Nonsterile, supplied 100 per pack, with each filter labeled with its membrane material and pore size.
These filters provide dependable, reproducible filtration that protects analytical instruments and preserves sample quality. The low hold-up volume minimizes sample loss, while the welded housing maintains filter integrity throughout each run. Clear labeling on every device supports easy identification even outside the original packaging.
