Thumbnail Filmstrip of Nylon Syringe Filters w/ Glass Fiber Prefilter, 0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk Images
Featuring a multilayer construction that pairs a naturally hydrophilic 0.45um Nylon membrane with a graded glass fiber (GF/F) prefilter rated at 0.7um, this 25mm syringe filter is built to push heavily loaded and viscous samples through with minimal force. The two layers of glass fiber depth media capture sediment and grit upstream, protecting the downstream Nylon membrane so the device resists clogging and processes larger sample volumes than a standard single-layer filter. The clear polypropylene housing carries a 25mm membrane within a 30mm body and provides a Female Luer Lock inlet with a Male Luer Slip outlet for secure, leak-free connections.
Key Nylon Membrane Characteristics
- Naturally hydrophilic Nylon membrane wets readily with aqueous and many organic solutions, requiring no pre-wetting
- 0.45um pore size delivers clarification and particulate removal for analytical sample preparation
- Broad chemical compatibility with aqueous solutions, alcohols, esters, and bases
- High mechanical strength and dimensional stability for consistent, repeatable filtration
- Graded glass fiber depth prefilter (0.7um) handles high particulate loads and viscous samples to prevent premature clogging
Key Construction Characteristics
- Clear polypropylene housing, 25mm membrane diameter within a 30mm housing diameter
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip)
- Effective filtration area of 4.63 cm squared
- Maximum operating temperature of 90 degrees C and maximum operating pressure of 75 psi
- Nonsterile, supplied 500 per pack
The combination of an upstream glass fiber depth medium and a downstream Nylon screen membrane delivers fast, reliable filtration of demanding samples while maintaining sample integrity. By absorbing the particulate load that would otherwise blind a conventional membrane, this device lets you process larger and harder-to-filter samples with a single filter. The result is clean, clear filtrate suitable for chromatography and other instrument analyses.

- Prefiltration of Heavily Loaded Samples The graded glass fiber depth media trap sediment and grit upstream, enabling filtration of high-particulate liquids that would quickly clog a standard membrane.
- Sample Clarification The 0.45um Nylon membrane clarifies aqueous and organic solutions to remove fine particulates before analysis.
- HPLC and GC Sample Preparation Produces clean, particle-free filtrate to protect columns and instruments during chromatographic sample prep.
- Viscous and Large-Volume Sample Filtration The multilayer design allows users to filter hard-to-process samples larger than 10 mL with reduced force.
- Filtration of Aqueous and Alcohol Solutions The hydrophilic Nylon membrane wets readily for efficient processing of aqueous and alcohol-based solutions.
- Environmental and Food/Beverage Sample Prep Suited to turbid or sediment-rich matrices common in environmental, food, and beverage testing laboratories.
