LabExact Grade CFP4 Qualitative Cellulose Filter Paper 0.21 mm Thick, 7.0 cm Dia., 25 um, 100 PK

Grade CFP4 has the fastest flow rate demonstrated by any of the qualitative cellulose filter media resulting in a low retention rate of approximately 25 um. Very commonly used as the first media in a multi-stage filtration process. Ideally suited for use in organic extractions and biological fluid separation processes. Often specified in air monitoring applications where the entrapment of fine particulate is not required.
