Product Description
FilterMAX™ Syringe Filters, Nylon with Glass (GF) Prefilter, 25mm, 0.22um, case of 1000
Nylon Syringe Filters with Glass Fiber Prefilter for High-Particulate Samples
Loading a heavily particulate sample onto a plain 0.22µm membrane clogs it fast, and you end up burning through filters just to get one clean injection. The glass fiber prefilter on these FilterMAX nylon filters catches the coarse stuff first, so the nylon membrane stays open longer and you get more sample through per filter.

Compatible With / Replaces
This is designed to be compatible with MilliporeSigma's Millex-GN 25mm nylon syringe filter with glass fiber prefilter (0.20µm, non-sterile). Pore size rounding (0.20µm vs. 0.22µm) is a labeling convention shared across the industry, and housing material isn't independently confirmed on our sheet, so we're not calling this a direct replacement.
FAQ
What's the benefit of the glass fiber prefilter?
It captures larger particulates before they reach the nylon membrane, so you get more sample volume through each filter before it clogs.
Is this good for both aqueous and organic samples?
Yes, nylon is hydrophilic and handles a broad range of solvents, though it's not recommended for strongly acidic samples.
What syringes does this fit?
Standard luer-lock syringes.
Is this filter autoclavable?
Yes.
What's the pack size?
10 packs of 100, 1,000 filters total per case.
