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.
Features of Grade 43 Lab Grade Filter Paper
Comparable to Whatman Grade 43 Especially suitable for gravimetric analysis The maximum ash content of a high purity filter is 0.009% Fast medium filtration speed and nominal particles retain a rating of 16 microns
Advantages of Chemical Filter Paper BIO-43
ISO9001 & CE Double approved Made of cellulose and high cotton wool Whatman equivalent quality but competitive price Full range of diameter Lowest ashless content: < 0.007% High purity and stable performance
