Qualitative filter paper is generally manufactured from cellulose fibers. Qualitative filter paper is designed to perform separation by entrapping particulates within the random matrix of cellulose fibers within the depth of the fitler media. This filter paper media is widely used in methods requiring the determination and identification of particulate in both liquids and gas. Also natural fiber qualitiative filter paper is commonly used to clarify liquid samples.
Qualitative filter paper is also available in fluted grades, which are easier to use and more convenient than flat filters when used in a filter funnel. This format reduces your preparation time due to its sharply creased, pre-folded pattern. Widely used for general laboratory separation and clarification applications as well as for soil analysis fitration methods.
