LabExact® Grade CFP4 25um Qualitative Cellulose Filter Paper, 5.5cm, 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 ...

These cellulose filters create a hydrophobic barrier that can replace a separatory funnel to separate organic solvents from aqueous phase. This grade demonstrates a fast flow rate with similar retention to our Qualitative Grade CFP1 filter paper.Retention: 11µmThickness: 0.20mmBasis weight: 88.0g/m2This paper is treated with immobilized silicone which allows solvent to pass and retains aqueous phase. Widely used in environmental studies and reducesseparation time significantly compared to separatory funnel. Quadrant fold or cone fold for use in a filter funnel or simply drop the ...

Very widely used filter media demonstrating retention of approximately 11µm and medium flow rate. Used in a broad range of laboratory and environmental applications, this media is ideally suited in separating lead sulfate, calcium carbonate and calcium oxalate precipitates. This media is the standard for agricultural procedures such as soil and seed sample testing. Also, it is commonly used as a separation media in the food and beverage industry to extract liquids from solid samples. Due to the consistent bright white color of this media, it is ideal for photometric stain intensity ...

Very fast flow rates and loose retention characteristics make this grade ideal for initial separation of gelatinous precipitates. 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.
