Thumbnail Filmstrip of PVDF Syringe Filters, 0.7/0.45um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 50/Pk Images
Featuring a multi-layer construction that pairs a graded glass fiber prefilter with a hydrophilic 0.45um polyvinylidene fluoride (PVDF) final membrane, this 25mm syringe filter is built to clarify viscous and high-particulate samples that would quickly clog a single-membrane device. The 0.7um glass fiber depth layer captures coarse sediment and grit before the sample reaches the 0.45um PVDF membrane, allowing more volume to pass with less plunger force. The clear polypropylene housing carries a 30mm diameter and offers a 4.63 cm2 effective filtration area, while Luer-Lok inlet and Luer Slip outlet connections fit standard syringes. Supplied nonsterile in packs of 50.
Key PVDF Membrane Characteristics
- Hydrophilic PVDF final membrane with a 0.45um rated retention for dependable sample clarification
- Integrated graded glass fiber prefilter (0.7um nominal) for high particulate loading and reduced clogging
- Multi-layer depth-plus-membrane structure that lets a single device process samples that would otherwise need several standard filters
- Low protein binding PVDF chemistry suited to aqueous and organic solutions
- Smooth, low-force filtration even with heavy, hard-to-filter samples
Key Construction Characteristics
- Clear polypropylene housing, 30mm diameter
- Luer-Lok inlet and Luer Slip outlet connections
- Effective filtration area of 4.63 cm2
- Maximum operating temperature of 90 degrees C (194 degrees F)
- Maximum operating pressure of 75 psi; supplied nonsterile, 50 per pack
The combined prefilter and membrane design delivers consistent flow and protects the final 0.45um layer from premature blinding, maintaining throughput across challenging matrices. The robust polypropylene housing withstands routine handling and a broad range of solvents, while the hydrophilic PVDF membrane preserves sample integrity for downstream analysis. The result is reliable particulate removal and clarification with fewer filter changes per sample.

- Sample Clarification Removes sediment and particulate from viscous or heavily loaded liquids ahead of analysis.
- HPLC and UHPLC Sample Prep Clarifies samples to protect columns and instruments, though it is not a sterilizing-grade filter.
- Filtration of Aqueous and Organic Solutions Handles both water-based and solvent-based samples thanks to the PVDF membrane and polypropylene housing.
- High-Particulate Sample Processing The graded glass fiber prefilter loads heavy grit so a single device replaces multiple standard filters.
- Environmental Sample Preparation Prepares sediment-rich field and water samples for downstream testing.
- Protecting Downstream Membranes Acts as a prefilter to extend the life of finer membranes in multi-stage filtration.
