Product description
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.
Qualitative grade applications and descriptions:
| CFP1 grade Very widely used filter media demonstrating retention of approximately 11 µm 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. |
| CFP2 grade A more retentive and absorbent media than CFP1, with approximately 8 µm 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. |
| CFP4 grade The fastest flow rate demonstrated by any of the qualitative cellulose filter medias resulting in a low retention rate of approximately 25 µm. 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. |
| CFP5 grade Filtration of very fine particulate and clarification with applications in environmental sciences and chemical analysis. |
| CFP200 grade Pure cotton 1-5 micron retention, slow flow, smooth surface. |
| CFP201 grade Pure cotton 7-14 micron, medium flow, smooth surface. |
| CFP202 grade Cotton with strengthening agent, 15-19 micron retention, medium-fast flow, crepe surface. |
| CFP226 grade Cotton with strengthening agent, 20-25 micron retention, fast flow, crepe surface. |
| CFP230 grade Cotton with strengthening agent, 30 micron retention, very fast flow, crepe surface. |
| CFP802 grade Cotton with strengthening agent, 15 micron retention, fast flow, crepe surface, fluted folds. |
