Thumbnail Filmstrip of Nylon Syringe Filters, 0.7/0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, Clear, 50/Pk Images
Featuring a multi-layer construction that pairs a graded glass microfiber and glass fiber prefilter stack with a 0.45um hydrophilic Nylon final membrane, these 25mm syringe filters clarify viscous and heavily particulate-laden samples that would quickly clog conventional single-layer devices. The 0.7um prefiltration layers capture sediment and grit upstream of the 0.45um membrane, allowing the user to push the syringe smoothly while protecting downstream analytical equipment. The clear polypropylene housing offers a 4.63 cm² effective filtration area and withstands a maximum operating temperature of 90°C and a maximum operating pressure of 75 psi.
Key Nylon Membrane Characteristics
- Naturally hydrophilic Nylon membrane wets out readily for filtration of aqueous and alcohol-based solutions without prewetting.
- A 0.45um pore size delivers reliable sample clarification and particulate removal ahead of analytical instrumentation.
- A graded 0.7um glass fiber and glass microfiber prefilter stack handles high particulate loads to extend membrane life.
- The multi-layer design lets one filter replace three or more standard syringe filters on hard-to-filter samples.
- Broad compatibility supports filtration of aqueous, organic, and alcohol solutions.
Key Construction Characteristics
- Clear polypropylene housing with a 30mm housing diameter and a 25mm membrane.
- Female Luer Lock inlet and Male Luer Slip outlet (Luer-Lok/Luer Slip) for secure syringe connection and dispensing.
- Supplied nonsterile, 50 filters per pack.
- Effective filtration area of 4.63 cm².
- Rated to a maximum operating temperature of 90°C and a maximum operating pressure of 75 psi.
The graded prefilter and Nylon membrane combination maintains consistent flow even with the heaviest sediment, reducing the force needed to complete filtration. By separating grit and particulates before the final membrane, the device protects sample integrity and downstream columns. The result is dependable, repeatable clarification of challenging samples in a single pass.
