Description of Quantitative Chemical Filter Paper Grade 43
Hawach chemical filter paper BIO-43 is a star product equivalent to Whatman’s Grade 43 with a more competitive price, which has a moderate retention rate and flow rate (16μm). We are the leading roll filter paper suppliers in both innovative design and high-quality products. Particle retention between medium flow filter paper BIO-40 and ashless filter paper BIO-41, but twice as fast as BIO-40.
Lab grade filter paper is particularly suitable for use in Buchner funnel filtration. Its tough, smooth surface makes it easy to recover sediment. The hardened ashless filter paper is acid-hardened and has high wet strength and chemical resistance, and the ash content is extremely low. The tough surface makes these filter papers suitable for a variety of demanding filtration steps. As a roll filter paper supplier, Hawach provides the full range size of the chemical filter paper.
BIO 43 is a medium speed filter paper used for sample collection in food analysis, air pollution monitoring, soil analysis, and inorganic analysis in the minerals, construction industry, and steel industries.
