Thumbnail Filmstrip of Nylon Syringe Filters w/ Glass Fiber Prefilter, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 10/Pk Images
Featuring a hydrophilic Nylon membrane backed by a two-layer glass fiber prefilter stack, this 25mm multilayer syringe filter clarifies heavily loaded and viscous samples that would quickly clog a standard single-layer device. The graded 0.7um glass microfiber and glass fiber prefilters trap sediment and grit upstream of the 0.45um Nylon final membrane, so the user can push the syringe smoothly through difficult samples with less force. The PFAS-free construction makes it well suited to trace analytical work where fluorinated background contamination must be avoided.
Key Nylon Membrane Characteristics
- Naturally hydrophilic Nylon membrane wets out without surfactants, supporting aqueous and organic solvent solutions.
- 0.45um pore size delivers reliable clarification and particulate removal ahead of chromatography and instrument analysis.
- Two-layer glass fiber prefilter (0.7um) handles high particulate loads, processing significantly more sample volume than filters without prefilters.
- Broad chemical compatibility with esters, bases, and alcohols.
- PFAS-free materials reduce the risk of fluorinated background interference in trace-level analysis.
Key Construction Characteristics
- Clear polypropylene housing permits visual confirmation of sample flow.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
- 25mm membrane diameter with a 4.63 cm² effective filtration area.
- Nonsterile, supplied 10 per pack.
- Rated to a maximum operating temperature of 90 degrees C and a maximum operating pressure of 75 psi.
The graded prefilter and final membrane combination delivers consistent flow and high throughput even with challenging matrices, reducing the need for a separate prefiltration step. Integrity-tested housing welds help eliminate filter bypass, protecting sample integrity from inlet to outlet. The result is a cleaner filtrate and dependable performance across demanding sample preparation workflows.
