Microfiltration membranes for pharmaceutical manufacturing.

In the pharmaceutical industry, microfiltration membranes are commonly used to purify liquids in processes, such as water for injection, and to remove contaminants from raw materials and intermediate products. Some membranes are also used for sterile filtration in order to produce aseptic process fluids, such as media and buffers, and remove microorganisms and particulates from finished products. In many processes, using membranes for microfiltration is a necessity to meet rigorous quality standards.


Pharmaceutical manufacturers demand consistent, controlled quality in their microporous membrane performance—the kind you can expect from 3M.  Our consistent, high-quality, microporous membranes feature high flow rates and flux performance to remove particles and specific microorganisms. The consistency of the membrane from batch-to-batch offers advantages in its application. This is because the filters or cartridges made from it consistently perform well, allowing for a stable process, even when a filter or cartridge is replaced.

A varied and versatile membrane portfolio.

With advanced manufacturing capabilities and decades of expertise across industries, 3M has developed an expansive membrane product portfolio. Our application engineers work closely with filtration manufacturers, supporting their efforts to meet objectives efficiently. In pharmaceutical filtration, stringent regulations are important to consider. 3M's diverse membrane portfolio makes it easy to identify a solution that aligns with your use-case requirements.
