LabExact® Grade CFP1 11um Qualitative Cellulose Filter Paper, 3.2cm, 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. Sold in package quantity of 100.

Qualitative cellulose filter papers perform separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media. This media is widely used in methods requiring the determination and identification of particulate in both liquids and gas. Also this natural fiber filter paper is commonly used to clarify liquid samples. Which are easier to use and more convenient than flat filters when used in a filter funnel. This format reduces your preparation time due to its sharply creased prefolded pattern. Widely used for general laboratory separation and ...

Grade CFP3 is virtually identical to CFP1, but twice as thick resulting in a significantly slower flow rate with a retention of approximately 6 um. This media does not clog as easily as the other qualitative cellulose types, which allows for much higher sample volume usage. This media also demonstrates very high levels of absorbency, permitting the media to be used as a sample conveyance substrate.

A more retentive and absorbent media than CFP1, with approximately 8µm and a medium to slow flow rate. This media is ideal for general filtration and absorbent conveyance. Commonly used in plant growth trials and monitoring pre-isolated contaminants in air and gas. Diameters up to 18.5cm are packaged in a convenient dispenser box which stores and dispenses product easily for lab bench or shelf storage. Helps keep product free of debris and damage during use.

Fluted Grade CFP2 filter paper is easier to use and more convenient than flat filters when used in a filter funnel. 8um retention with medium-slow flow rate. Very high loading capacity. Sharply creased, smooth bright white filters are neatly packaged in groups of 10, ready to use. Applications include general laboratory separation & clarification and soil analysis methods.
