Wet Strengthened Chemistry Filter Paper Grade: BIO-113

Description of Wet Strengthened Chemistry Filter Paper

Hawach BIO-113 chemistry filter paper is a star product equivalent to Whatman’s Grade 113 at a more competitive price. Wet strengthened filter paper sheet grade 113 has high wet strength due to the addition of a small quantity of chemically stable resin. BIO-113 wet strengthened filter paper has a very high load capacity for filtration, making this filter ideal for use with coarse or gelatinous precipitates.

Qualitative chemistry filter paper surface is wrinkled and is commonly used to filter resin solutions. Wet strengthened filter paper has ultra-high loading capacity with 30µm pore size, but 10 micron filter paper grade 91 is 10um. Filter paper chemistry is usually used for coarse particle filtration or gel precipitation filtration and for vacuum filtration of viscous liquids. In schools, filter paper chemistry is also used to filter sediment.

Features of Filter Paper Sheets Grade BIO-113

• Fast flow filter paper of the qualitative grades and has a creped surface;
• With a creped surface;
• For filtration of large particle filters or gelatinous precipitates;
• Don’t recommend using chemistry filter paper in applications of Kjeldahl estimations;
• Filter paper sheets in the full range of diameter: 70, 90, 110, 125, 150, 180, 185, 240, 270, and 300mm.

Advantages

• Minimum ash-free content is: < 0.1%;
• Very tough, with high wet strength;
• High purity and consistent performance;
• Thick chemistry filter paper in the qualitative range;
• Normal qualitative applications will not introduce any significant impurities into the filtrate;
• Same quality as Whatman, but super competitive price;
• A full range of filter paper chemistry diameters provide, and customized types and sizes are available.

Applications

• Conventional filtration;
• Citric acid and sodium in drugs;
• Determination of volatile acids in flour and maltose;
• Monitoring air pollution with reagent immersion;
• Biological liquids or organic extracts – such as fat, are quickly purified by.
