Description
Description of Wet Strengthened Filter Paper Grade BIO-91
Hawach Scientific Co., Ltd BIO-91 10 micron filter paper is a star product equivalent to Whatman’s Grade 91. As a wet strength supplier, we have a more competitive price and a proper retention rate and flow rate (10μm). BIO 91 filter paper discs are very tough and have high wet strength. In general qualitative applications, no significant impurities are introduced. However, the resin contains nitrogen, so it should be noted that it cannot be used for the determination of Kjeldahl. Some wet-strength qualitative filter papers have a folded form.
As a filter paper supplier, Hawach complete diameter range of 70, 90, 110, 125, 150, 180, 185, 240, 270, and 300mm. Wet strength grade 91 filter paper has medium filtration speed, if you prefer a faster speed, you can choose filter paper sheets BIO-113. Hawach is a major wet strength manufacturer in the global filter paper market. The higher the degree of folding of the 10 micron filter paper, the higher the surface area that can be provided, and the better the filtering effect, but the wet strength manufacturer suggests being careful not to over-fold and cause the filter paper to break.
