LabExact® Weighing Paper, Nitrogen Free, Squares 3" x 3", 500/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.

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 ...

Grade CFP44 is very similar to Grade CFP42 but demonstrating a slightly wider retention rate within a similar flow rate. Typically used in the analysis of samples requiring separation of very fine precipitates. . Retention of approximately 3 um. Extremely low ash content of

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 ...

Virtually identical to CFP1, but twice as thick resulting in a significantly slower flow rate with a retention of approximately 6µm. 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. 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.
