Photo of Ahlstrom 542 Medium Flow Rate Pre-Pleated Filter Paper
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 12.5cm to 50cm diameters. Grade 542 has a medium flow rate filtering speed with 2 µ particle retention.
