Hawach BIO-42 filter paper is equivalent to Whatman filter paper Grade 42 with a more competitive price, which has a high retention rate and a slow flow rate (pore size: 2.5μm). The finest particle retention in all Hawach laboratory filter paper. Commonly used for the determination of the elemental content of minerals such as barium sulfate, metastannic acid, calcium carbonate, barium carbonate, filtration of gasoline or organic solvents, and filtration preparation of spectral and chromatographic samples, such as atomic absorption (AAS) determination of the second laurel in the feed.
Laboratory filter paper is a medium-speed filter paper that retains fine particles in cellulose filter paper. Commonly used for the analysis of fine particle sediments such as barium sulfate, metastannic acid, and calcium carbonate. Filter paper used in the laboratory can use the determination of the content of dibutyltin acid. Similarly, cellulose filter paper grade 44 is also possible.
