Qualitative Filter Paper Grade F108
These quantitative filter papers are manufactured from high quality cotton linters using pure water and are further treated with dilute acid to remove any remaining organic and inorganic impurities. The papers are suitable for routine gravimetric analysis and typical preparation of samples for use in analysis involving instrumental techniques. All quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter.
Paper Characteristics
Slow flow rate for fine retention. High purity (100% cotton). For water analysis, biological products, fine precipitates, used in Buchner funnels.
This grade is a slow flowing filter designed to retain fine particles encountered in qualitative analysis. These F108 filters are widely used for water analysis, biological products, and fine precipitates such as coldprecipitated barium sulfate. Also, used in Buchner funnels and to clarify cloudy suspensions.
