Grade CFP4 25 um Cellulose filter paper, cut 9.0cm dia. 100/pk Qualitative grade

CFP4: The fastest flow rate demonstrated by any of the qualitative cellulose filter media’s resulting in a low retention rate of approximately 25µm. Very commonly used as the first media in a multi-stage filtration process. Ideally suited for use in organic extractions and biological fluid separation processes. Often specified in air monitoring applications where the entrapment of fine particulate is not required.

Qualitative and quantitative cellulose filter paper is
available in a wide range of grades to meet different
separation applications.

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.

Filter Media: Nomenclature is serialized and no indication of grade or quality.
Furnish: The raw materials used in the manufacture of the wet laid product.
Ash content: Dry method, determined in exposure at 900ºC in muffle furnace.
Retention: Nominal retention of particulate at 98% efficiency in liquid.
Flow: Liquid flow rate speed relative to other comparable products listed in this product alignment.
Basis weight: Nominal weight of material per meter2 indicated “gram weight” unit of measure at 8% moisture.
Thickness: As measured under 4 psi using TAPPI method T411
Flat/Fluted: Flat stock is supplied as sheets, rolls or die cut parts. Fluted is ¼ or ½ quadrant funnel folding.
Surface: Stated as relative to comparable products listed in this product alignment.
Brightness: Stated as relative to comparable products listed in this product alignment.
