Is commonly used in quantitative and qualitative analysis, filter papers must be closely matched to the application according to its physical characteristics Many sizes, materials, types, and grades of filter paper are available for various applications. GIMO® filter papers use only the highest quality raw materials for high reproducibility and uniformity. GIMO® cellulose filter papers are manufactured from high-quality cotton liners treated to achieve an α-cellulose content >98%.
