Thumbnail Filmstrip of Glass Fiber Syringe Filters, PFAS-Free, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Featuring a hydrophilic borosilicate glass fiber depth medium with a 0.45um nominal particle retention, this PFAS-free syringe filter delivers rapid prefiltration of heavily loaded aqueous and organic samples. The graded depth structure captures particulates across a range of sizes, providing high dirt-holding capacity and high flow while protecting downstream membranes and instrumentation. A transparent polypropylene housing offers broad chemical compatibility, and the female Luer-Lok inlet with male Luer Slip outlet connects securely to standard syringes. Each unit is supplied nonsterile in packs of 100.
Key Glass Fiber Media Characteristics
- Naturally hydrophilic borosilicate glass fiber depth medium that wets readily with aqueous samples
- 0.45um nominal particle retention suited to clarification and prefiltration rather than absolute sieving
- Graded depth structure provides high particulate loading capacity for turbid and heavily loaded samples
- High flux and high flow rate with strong mechanical strength under filtration pressure
- Low extractables and resistance to high temperatures, acids, and alkalis
Key Construction Characteristics
- Transparent polypropylene housing with broad chemical compatibility
- Female Luer-Lok inlet and male Luer Slip outlet for secure syringe connection
- 25mm membrane diameter for sample volumes up to approximately 50 mL
- PFAS-free construction verified for trace PFAS analysis
- Nonsterile, supplied 100 per pack
The graded glass fiber depth medium maintains consistent flow even as particulate load increases, reducing clogging and preserving sample integrity. Low extractables and verified PFAS-free materials make this filter well suited to applications where background contamination must be minimized. Reliable construction and accurate labeling support reproducible results across routine and demanding sample preparation workflows.
