Quantitative Cellulose Filter - Grade C and 54
 |
Grade C - Fine porosity fast flow rate with a 1.2µm size particle retention. Primarily used for RIA procedures and harvesting lymphocytes. Binderless borosilicate glass microfiber.
Grade C has several sub groups as follows 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. CFP2: 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. About different glass filter grades See all Lab Filters |
