Hawach BIO-41 ashless filter paper is a star product equivalent to Whatman’s Grade 41 with a more competitive price, which has a low retention rate and fast flow rate (20-25μm).
Ashless filter paper in the manufacturing process, the pulp is treated with hydrochloric acid and hydrofluoric acid and washed with distilled water to remove most of the impurities in the paper fiber, so there is little residual ash after burning, which has little effect on the analysis results. It is important to filter paper for laboratory use.
