Product Description
FilterMAX™ Syringe Filters, Hydrophilic PTFE, 25mm, 0.45um, case of 1,000
FilterMAX™ Hydrophilic PTFE Syringe Filters, 25mm, 0.45µm, Case of 1,000
When you're filtering higher-particle or higher-flow samples and don't need the tighter 0.22µm cutoff, a 0.45µm filter moves faster and clogs less. This hydrophilic PTFE version wets instantly with aqueous samples and still handles harsh organic solvents, so one filter chemistry covers both sample types.
No hidden fees, ever. Bulk case pricing, always-free ground shipping, and Maryland-based fulfillment for fast delivery.

FAQ
What's the difference between this and the 0.22µm version?
Same PTFE membrane chemistry, this one uses a 0.45µm pore for faster flow and less clogging on higher-particle samples.
Does this need pre-wetting?
No, it's hydrophilic PTFE and wets on contact with aqueous samples.
Is this filter sterile?
No, non-sterile.
Is it autoclavable?
Yes.
What's the case pack size?
1,000 filters.
