Grade CFP41 Qualitative Cellulose Filter Paper, 20µm, 90mm, Fast Flow, 100/Pk SKU: LE-CFP41-090

Featuring qualitative cellulose fiber technology delivering exceptional flow rates for rapid separation of gelatinous precipitates and coarse particulate matter. Very fast flow rates and loose retention characteristics make this grade ideal for initial separation of gelatinous precipitates while maintaining 20µm particle retention with ultra-low ash content below 0.01%. Qualitative papers perform separation by trapping the particulates within the random matrix of cellulose fibers located in the depth of the media. These papers are used in methods requiring the determination and identification of particulates in both liquid and gas samples.
