Product Description
FilterMAX™ Syringe Filters, PES, 25mm, 0.45um, case of 1000
Low-Binding PES Syringe Filters for Protein and Biologics Prep
Protein-rich and aqueous samples have a way of clogging filters that aren't built for them, costing you time and sample. FilterMAX PES syringe filters use a low-protein-binding polyethersulfone membrane that lets aqueous samples pass cleanly, so your filtration step doesn't become the bottleneck in your prep.
No hidden fees, ever: free ground shipping, no handling fees. Just the product and a clean invoice!

This matches Whatman Puradisc 25 PES syringe filters (0.45µm, catalog 6780-2504) on pore size, diameter, membrane chemistry, and luer connection type. Whatman's sheet confirms a polypropylene housing; ours doesn't explicitly restate housing material for this SKU, so we're calling this designed to be compatible with rather than a confirmed direct replacement.
FAQ
- What's the housing made of?
- PFAS-free with no color additives. Exact housing material isn't restated on this specific listing (SPEC NEEDED); contact us if you need it confirmed in writing for a validated method.
- What syringes does this fit?
- Standard luer-lock syringes.
- Is this membrane sterile?
- Sterility isn't specified for this SKU (SPEC NEEDED). Contact us if sterile PES filters are what you need and we'll point you to the right item.
- Why choose PES over nylon or PVDF?
- PES combines low protein binding with faster flow rates than PTFE or PVDF, which is why it's a common default for aqueous biological sample prep.
- What's the pack size?
- Case of 1,000 total filters.
