Grade CFP5 Cellulose Filter Paper, Qualitative, 2.5µm Retention, 70mm, Hydrophilic, 100/Pk SKU: LE-CFP5-070

Featuring natural cellulose fiber technology delivering filtration of very fine particulate and clarification with applications in environmental sciences and chemical analysis. Retention of approximately 2.5µm provides precise separation while maintaining optimal flow rates for routine analytical procedures. Qualitative cellulose filter papers perform separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media, maximizing your filtration efficiency across diverse laboratory applications.
