Pleated (Fluted) Filter Paper

(49)

Ahlstrom-Munksjö offers a full range of standard pleated (fluted) 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-Munksjö’s pre-pleated fluted grades can save valuable time and maximize the efficiency of the laboratory filter system. Pleating (fluting) 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.
