Application Reference by Grades of Cellulose Qualitative Cellulose Grade CFP1

Very widely used filter media demonstrating a 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. Grade CFP2 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. Grade CFP3 Virtually identical to CFP1, but twice as thick resulting in a significantly slower flow rate with a retention of approximately 6 µm. 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. Grade CFP4 The fastest flow rate demonstrated by any of the qualitative cellulose filter media 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. Grade CFP5 Filtration of very fine particulate and clarification with applications in environmental sciences and chemical analysis. Grade CFP6 Very similar basis and thickness to CFP5 but with a slightly less retentive porosity. Also, due to the furnish of this paper the ash content is higher than the balance of the qualitative line. Material is commonly specified in environmental applications. Quantitative Cellulose Grade CFP40 Demonstrating medium retention and flow rates, this media is widely used in many general quantitative procedures in both liquid and gas. These procedures include: standard environmental test procedures such as soil sample analysis and the collection of trace elements and radionuclides in air samples. Also used in liquid food tests for determination of sediments, primary analysis of cements and slurries and sample preparation prior to spectrophotometry. Grade CFP41 Very fast flow rates and loose retention characteristics make this grade ideal for initial separation of gelatinous precipitates. Grade CFP42 This media demonstrates an extremely high retention rate for a cellulose filter media. Its uniquely high retention rate makes it ideal for any gravimetric analysis of very fine precipitates.

Grade CFP43 Positioned as an intermediate within the quantitative cellulose family, this grade demonstrates medium retention and flow rates. It is ideal for gravimetric analysis of soil samples, surface water testing procedures and used in air sample monitoring equipment. Grade CFP44 Very similar to 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. Specialty Cellulose Grades Technical specifications for these grades can be accessed at www.iwtremont.com. Grade CFP41a (Air Monitoring) This quantitative cellulose filter paper is primarily used in air monitoring applications and gravimetric analysis procedures. They perform separations by entrapping particulate within the random matrix of cellulose fibers within the depth of the media. This media family is also widely used in methods to prepare samples for further testing using many types of instrumentation. Due to the hardened surface, this material is suited for smear and wipe applications as well. These ashless filter papers are manufactured from refined pulp and linters. They are acid washed and have an extremely low ash content of <0.01%. Chromatography Paper This unique media is an ultra-high purity cellulose filter paper. The proprietary production methods employed produce a media which demonstrates a highly durable surface texture without the high level of organic extractables common to traditional acid-hardening processes. The alpha cellulose content is a minimum of 97.5% or above and is single source. This media demonstrates excellent lot-to-lot reproducibility. Material chemistries are verified against a standard using GC techniques prior to paper making process. Blotting Paper This media is a smooth surface, bright white cellulose filter paper. The material is manufactured from carefully selected, fully bleached and chemically-free pure cellulose fiber without additives or binder. General laboratory blotting applications require smooth, flat paper stock demonstrating high absorption and wicking characteristics. Some of these applications include: membrane backing, sample collection and conveyance of pastes and gels, wicking media for blot apparatus, draw down tests of liquid samples such as paints and adhesives. The media is also specified in TAPPI T-205 sp-06-Forming handsheets for physical tests of pulp, section 3.9-“Blotting paper”. Also specified in Development of USPS laboratory and pilot-scale testing protocols, 2000, Appendix 1A II, no. 8, Materials, “Blotters”.

Glass Microfiber

Binderless Glass microfiber filters offered in this product range are produced from 100% borosilicate glass microfiber without the use of binders or strengthening agents. These filters offer many advantages in a wide range of analytical applications. The fibers used to manufacture these depth filters are smooth and uniform. This permits their characteristically high flow rates while allowing retention of exceptionally small particles and high load capacity. These characteristics are particularly important in applications involving high concentrations of particulate or gelatinous substances. In choosing the appropriate filter for a specific application, careful consideration should be given to the physical form and concentration of the material to be captured by the filter.

Binderless glass microfiber media is available in many formats such as custom die-cut shapes, disks, sheets, rolls and thimbles.

FEATURES • Fastest flow rate • High load capacity • Retention of particles to sub-micron size • Broad temperature range • Use in liquid and gaseous filtration • Inert fiber composition • Free of binders or additives APPLICATIONS Applications may vary by grades of material. Please see inside guide for details.

DEPTH FILTRATION

Depth filtration categorizes filter media that traps particulate within the random matrix of fibers found within the thickness of the media. The efficiency rating of the filter is characteristic of the complex void space structure that develops as the fibers overlap. The fibrous material within the filter is commonly glass microfiber, cellulose or polypropylene. In depth filters using glass microfiber, the purity of the filter is dictated by the presence of, if any, binder material that acts as a strengthening agent and aids in holding the fibers together. All of the media described in this brochure are 100% borosilicate glass and free of binders. Because of the characteristically high flow rates of depth filters, they are generally used in applications such as single and multi process removal of sediment and coarse particulate. Glass microfiber filters without binders are an ideal medium to entrap sediment for further analysis and counting due to the inert matrix. Also, depth filtration media are commonly used for prefiltration prior to surface filtration with substrates such as membranes.
