Filter Paper, Qualitative Grade CFP6, 3-4µm Retention and Slow Flow Rate, 9.0cm Diameter Cut, 100/pk

Qualitative Cellulose Filters

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.

Very widely used filter media demonstrating retention of approximately 11µm and medium flow rate. Used in a broad range of laboratory and environmental applications, this media is ideally suited in separating lead sulfate, calcium carbonate and calcium oxalate precipitates. This media is the standard for agricultural procedures such as soil and seed sample testing. Also, it is commonly used as a separation media in the food and beverage industry to extract liquids from solid samples.

IW Tremont Grade CFP3 Qualitative Filter Paper: Virtually identical to Grade CFP1, but twice as thick resulting in a significantly slower flow rate with a retention of approximately 6um. This media does not clog as easily as the other qualitative cellulose types, which allows for much higher sample volume usage. This media also demonstrates very high levels of absorbency, permitting the media to be used as a sample conveyance substrate.
