MMM membranes are super-micron filters which have pore sizes from one to ten microns. These asymmetric membranes are highly porous and inherently wettable without the use of additional wetting agents.

MMM membranes are low protein binding and have been certified to pass USP Class VI-121 °C plastics test for biological safety.

The patented asymmetric pore structure and manufacturing technique offer unique performance and consistency.
