Ahlstrom manufactures high quality analytical filter papers for use in specialty end use applications. These custom designed qualitative grades are manufactured from top quality cotton linters using ultra-pure, reverse-osmosis water. Ahlstrom specialty analytical filter papers include pleated and non-pleated grades and are found in applications such as seed, asphalt and beer testing. All grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter. Ahlstrom offers a full range of standard pleated grades that meet your needs from grades with rapid flow rates for filtration of viscous materials to grades with tight matrices for removal of fine precipitates. Ahlstrom's pre-pleated grades can save valuable time and maximize the efficiency of the laboratory filter system. Pleating improves the effective surface area increasing flow rate and loading capacity thus decreasing filtration time. Pleated circles are available in 12.5 cm to 50 cm diameters.
