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.
BIO-41 filter paper is the filtration of large particles or gel deposits. Ashless filter paper is also used for rapid flow rate determination of gaseous compounds in quantitative air pollution analysis. The difference between grade 40 medium flow filter paper, quantitative filter paper grade 41 has a fast filtration speed.
