Ahlstrom-Munksjö offers qualitative and quantitative filter papers for use in a variety of analytical methods. Our papers consist of greater than 95% super refined alpha-cellulose and linter fibers and are produced under tightly controlled manufacturing conditions to provide lot-to-lot reproducibility.
Qualitative and quantitative filters are available both as binder free and wet-strengthened (hardened) versions across a wide range of micron ratings and filtration speeds. Many standard and custom circle sizes are available. Some qualitative grades are available pleated or fluted, for greater convenience.
