CFP1 Cellulose Filter Paper, 12.5cm, Qualitative grade, 100-pk

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.  

CFP1 Characteristics: 

Grade CFP1 is a very widely used filter media demonstrating a retention of approximately 11 um 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. Non-Sterile.
