Glass Microfiber Filtration - Flat Stock Filter Paper
Depth filtration categorizes filter media that traps particulate within the random matrix of fibers found within the thickness of the media. The efficiency rating of the filter is characteristic of the complex pore structure that develops as the fibers overlap. The fibrous material within the filter is commonly glass micro fiber or polypropylene.
Used for the sterilization and filtration of liquids.
These high quality filters are available in traditional 13mm and 25mm sizes.
Available in many different filter media materials to meet your exact needs including :
