Product Description
FilterMAX™ Syringe Filters, Polypropylene, 25mm, 0.45um, case of 1000
Polypropylene Syringe Filters Built for Solvent-Heavy Sample Prep
Some sample matrices eat through membrane materials that aren't built for organic solvents, and a filter that partially dissolves into your sample is worse than no filter at all. Polypropylene membranes hold up against a wide solvent range, which is why they're a go-to for GC and HPLC prep involving harsher organics.
No hidden fees, ever: free ground shipping, no hazmat surcharges, no handling fees.

Compatible With / Replaces
This is designed to be compatible with Whatman's Puradisc depth polypropylene syringe filter (25mm, 0.45µm, non-sterile, 1000-pack). Diameter, pore size, membrane chemistry, sterility, and pack size all line up, though full pressure and flow-rate specs aren't independently confirmed on our sheet.
FAQ
Can this filter be used with organic solvents?
Yes, polypropylene membranes are built for broad solvent compatibility, including harsher organics that can degrade other membrane types.
Is this a hydrophobic or hydrophilic membrane?
Hydrophobic. It's better suited to organic and non-aqueous samples than water-based ones.
What's the pack size?
10 packs of 100, 1,000 filters total per case.
Is this sterile?
No, this is a non-sterile filter.
