Qualitative Analytical Filter Paper
We provide a variety of filter papers with different pore sizes and diameters. If you require a specific pore size or diameter that is not available or is currently out of stock, please contact us via email at info@labware.com.hk for further assistance with your order.
LabPro 's grades: QL01 | QL02 | QL03 | QL04 | QL05 | QL06 | QL597
These 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...).
