**셀룰로즈 정성 여과지

Qualitative papers perform separation by trapping the particulates within the random matrix of cellulose fibers located in the depth of the media.
These papers are used in methods requiring the determination and identification of particulates in both liquid and gas samples.

* CFP1: Very widely used filter media demonstrating a 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 measurement of air samples.
The media can also be impregnated with reagents for use in quantifying optical reflectance in gas detection procedures
Ash Content: <0.05%

* CFP2: A More retentive and absorbent media that 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.

* CFP3: 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.

* CFP4: The fastest flow rate demonstrated by any of the qualitative cellulose filter media´s resulting in a low retention rate of approximately 20-26µm.
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.
