Grade CFP40 Cellulose Filter Paper, Cut 11.0cm Diameter 100/pack Quantitative Grade

Product Category Information:

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

Qualitative Cellulose

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

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.

Qualitative Grades

CFP1: Very widely used filter media demonstrating retention of approximately 11 m 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.

CFP2: A more retentive and absorbent media than CFP1, with approximately 8 m and a medium to slow flow rate. This media is ideal for general filtration and absorbent conveyance. Commonly used in plant growth trials and monitoring pre-isolated contaminants in air and gas.

CFP3: Virtually identical to CFP1, but twice as thick resulting in a significantly slower flow rate with a retention of approximately 6 m. 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.

CFP4: The fastest flow rate demonstrated by any of the qualitative cellulose filter media's resulting in a low retention rate of approximately 25 m. 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.

CFP5: Filtration of very fine particulate and clarification with applications in environmental sciences and chemical analysis.

CFP6: Very similar basis and thickness to CFP5, but with a slightly less retentive porosity. Also, due to the furnish of this paper, the ash content is higher than the balance of the qualitative line. Material is commonly specified in environmental applications.

Quantitative Grades

CFP40: Demonstrating medium retention and flow rates, this media is widely used in many general quantitative procedures in both liquid and gas. These procedures include: standard environmental test procedures such as soil sample analysis the collection of trace elements and radionuclides in air samples. Also used in liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry.

CFP41: Very fast flow rates and loose retention characteristics make this grade ideal for initial separation of gelatinous precipitates.

CFP42: This media demonstrates an extremely high retention rate for a cellulose filter media. Its uniquely high retention rate makes it ideal for any gravimetric analysis of very fine precipitates.

CFP43: Positioned as an intermediate within the quantitative cellulose family, this grade demonstrates medium retention and flow rates. It is ideal for gravimetric analysis of soil samples, surface water testing procedures and used in air sample monitoring equipment.

CFP44: Very similar to CFP42 but demonstrating a slightly wider retention rate within a similar flow rate. Typically used in the analysis of samples requiring separation of very fine precipitates.
