SECO Grade CFP41 Cellulose Quantitative Filter Paper, 11 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. CFP41: Very fast flow rates and loose retention characteristics make this grade ideal for initial separation of gelatinous precipitates.
