Product Features

High Dirt-Holding Capacity

The thick glass fiber matrix captures large amounts of suspended particles, reducing filter clogging and extending the life of downstream membrane filters.

Superior Wet Strength

The binder resin reinforces the glass fibers, providing excellent mechanical strength even during filtration of large sample volumes.

Hydrophilic Surface

The naturally hydrophilic filter wets easily with aqueous solutions, allowing rapid filtration without additional wetting agents.

Excellent Flow Rates

The highly porous structure delivers fast filtration while maintaining efficient particle retention.

Depth Filtration

Unlike surface filters, contaminants are trapped throughout the thickness of the filter, allowing higher loading capacity and improved throughput.

Compatible with Vacuum Filtration

Suitable for use with standard 47 mm vacuum filtration assemblies, manifolds, and laboratory filtration systems.
