Thumbnail Filmstrip of Nylon Syringe Filters, 0.7/0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk Images
Featuring a multilayer construction that stacks graded glass fiber prefilters ahead of a 0.22um hydrophilic nylon final membrane, this syringe filter is built to process high-particulate, viscous, and hard-to-filter samples without clogging. The 0.7um prefilter stage captures sediment and grit while the 0.22um nylon membrane delivers clarified output, allowing the user to push the syringe smoothly even with heavily loaded samples. Each unit pairs a 25mm membrane within a clear polypropylene housing measuring 30mm in diameter, with a 4.63 cm2 effective filtration area and Female Luer Lock inlet to Male Luer Slip outlet connections.
Key Nylon Membrane Characteristics
- Naturally hydrophilic membrane wets out readily for aqueous and many organic solvent samples without the need for prewetting.
- Final 0.22um nylon layer provides fine clarification downstream of the prefilter stack.
- Graded glass fiber prefilter layers (0.7um) handle viscous and heavily sedimented samples to extend usable filter life.
- Multilayer no-clog design lets one filter do the work of three or more standard syringe filters.
- Broad sample compatibility suited to aqueous and alcohol solutions.
Key Construction Characteristics
- Clear polypropylene housing, 30mm diameter, with a 25mm membrane and 4.63 cm2 effective filtration area.
- Female Luer Lock inlet to Male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
- Nonsterile, supplied 500 per pack.
- Withstands a maximum operating temperature of 90C (194F) and a maximum operating pressure of 75 psi.
The graded prefilter stack maintains consistent flow under heavy particulate loads, reducing operator effort and the risk of premature clogging. The 0.22um final membrane delivers reliably clarified filtrate while preserving sample integrity. This combination makes the filter a dependable choice for demanding sample preparation where standard single-layer filters fail.

- Viscous Sample Filtration The graded prefilter stack and no-clog design process thick, hard-to-filter samples larger than 10 mL with less syringe force.
- Prefiltration of Heavily Loaded Samples Two layers of glass fiber prefilter separate sediment and grit, protecting the downstream nylon membrane from premature clogging.
- Analytical Sample Preparation Clarifies particulate-laden samples to a 0.22um endpoint ahead of instrumental analysis.
- HPLC and UHPLC Prep Removes fine particulates that would otherwise foul columns and detectors during chromatographic analysis.
- Environmental Sample Prep Handles high-turbidity aqueous samples typical of environmental testing workflows.
- Aqueous and Alcohol Solution Filtration The hydrophilic nylon membrane wets readily for filtration of water-based and alcohol solutions.
