Those grades are made with high purity cotton linters fibres and cellulose fibres (ash content of 0.06%). The qualitative filter papers allow to determinate with a great precision the nature of the filtered solutions and to check the composition of the samples. They offer better resistance to chemicals and moisture compared to standard filters and thus can be used for food, beverages, environmental analysis (air, soil, etc.).
