    Grade CFP1 cellulose filter paper, cut 18.5cm dia. 100/pk Qualitative grade

    CFP1: 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.

    Due to the consistent bright white color of this media, it is ideal for photometric stain intensity measurement of air samples. The media can also be impregnated with reagents for use in quantifying optical reflectance in gas detection procedures.

    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.

    Quantitative Cellulose Filters

    Quantitative cellulose filter papers are primarily used in gravimetric analysis procedures and perform separations by entrapping particulate within the random matrix of cellulose fibers within the depth of the media. This media family is also widely used in methods to prepare samples for further testing using many types of instrumentation. These very high quality filter papers are manufactured from refined pulp and alpha linters. They are acid washed and have an extremely low ash content.
