Whatman offers an extensive line of filter papers. The unique features of these filters make them the optimum choice for
many filtering techniques. Whatman maintains a guaranteed quality, reproducibility and uniformity for all its filters by using
only the highest quality raw materials. The filters are tested for basis weight, thickness, air flow and mechanical strength.
In addition, special parameters such as pore size, wicking rate, filtration performance and surface characteristics can be
measured as needed.
