SECO Grade CFP44 Cellulose Quantitative Filter Paper, 7 cm dia

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. 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.
