Qualitative and quantitative cellulose filter paper is available in a wide range of grades to meet different separation applications.
Qualitative cellulose filter papers perform separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media. This media is widely used in methods requiring the determination and identification of particulate in both liquids and gas. Also this natural fiber filter paper is commonly used to clarify liquid samples.
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 prefolded pattern. Widely used for general laboratory separation and clarification applications as well as for soil analysis methods.
