Mfg Item # : N0218.5CM
Advantec Qualitative Filter Papers are made of 100% cotton linter cellulose. Primarily used for clarifying and removing precipitates (ppt) and preparation for quantitative analysis. These papers can be used over a pH range from 0-12 and a maximum temperature of 120°C. Ash content of 0.1%. Papers have smooth surface, normal hardness (except Grade No. 101 have a creped surface). Grade No. 1 Retains coarse and gelatinous ppt with fast flow rate. Recommended for gas filtration, air pollution analysis, and general purpose. Nominal Retention: 6 µm. Grade No. 2 Retains medium crystalline ppt with high flow rate. General purpose filter. Nominal Retention: 5 µm. Grade No. 231 Retains crystalline ppt, moderate flow. Thin and slightly more retentive than No.1 general purpose paper. Nominal Retention: 5 µm. Grade No. 232 Collects medium to medium-fine ppt. Slow flow rate. Thin retentive paper. Nominal Retention: 3 µm. Grade No. 131 High retention efficiency for fine crystalline ppt like BaSO4. Slow flow. Higher wet strength and will withstand suction. Nominal Retention: 3 µm. Grade No. 235 Highest retention efficiency collecting very fine ppt. Very slow flow rate. Nominal Retention: 1 µm. Grade No. 101 Creped filter paper captures large particles. Fast flow rate. Excellent for seed germination and viscous fluids. Nominal Retention: 7 µm. Please Note: ALL Advantec items have a maximum 48 hour cancellation window. Any cancellations AFTER the 48 hour window will incur a restocking fee equal to the cost of the product.

GVS Filter Technology Part No. 1215544
Extend the life of final filters Pore sizes from 0.5 µm to 1.0 µm With or without binders Autoclavable PreSep prefilters are biologically inert and highly resistant to oxidizing agents and weak acids. Primarily used to extend the life of a final filter, they can also be used as a low-cost sample clarifier. Prefilters increase the speed of filtration by trapping large particles before they reach the final membrane filter. Frequency and cost of replacing the final membrane filters is reduced. Filters with binders are composed of borosilicate glass fibers woven into a porous matrix and bonded by an acrylic resin. The resulting filter reduces media migration and has the strength required for high-volume aqueous filtrations. Maximum operating temperature is 165°C (325°F). Glass prefilters without binders are designed to avoid binder extractables during solvent filtration or gravimetric analysis. Not recommended for temperatures exceeding 510°C (950°F). For upstream protection of a membrane within a filter holder, the use of a prefilter that is slightly smaller in diameter than the main filter allows the prefilter to fit inside the O-ring or filter funnel holder seal, ensuring a positive membrane seal. When used as the main filter medium, select a diameter of the same size as the filter holder to be used. Type G15 Glass Fiber Prefilters with Binders (4749A02 to A14) Nominal pore size- 0.5 µm High rentention efficiency Limited dirt-handling capacity Protection of 0.2 µm to 0.8 µm final filters Type G20 Glass Fiber Prefilters with Binders (4749A20 to A32) Nominal pore size- 1.0 µm Surface capture of particles Average retention efficiency Higher dirt-handling capacity Protection of 0.8 µm and larger pore size final filters Type G25 Glass Fiber Prefilters with Binders (4749A40 to A54) Nominal pore size- 1.0 µm Thickness approximately 3.5 times greater than G20 Depth particle capture Average retention efficiency Highest dirt-handling capacity Recommended for solutions with heavy contaminate loads Protection of 0.8 µm and larger pore size final filters Type G40 Glass Fiber Prefilters WITHOUT Binders (4638D60 to D68) Nominal pore size- 1.0 µm Average retention efficiency Highest dirt-handling capacity Recommended for solvent filtration, gravimetric analysis, contamination analysis of wastewater and industrial effluents TCLP Glass Fiber Filters WITHOUT Binders, 0.7 µm Pore Size (4749A72) Borosilicate glass fiber filters designed for use in U.S. EPA Method 1311 Toxicity Characteristic Leaching Procedure (TCLP). Federal regulations require the filters for this application be made of borosilicate glass fiber, contain no binder materials and have an effective pore size of 0.6 to 0.8 microns. GE TCLP glass fiber filters have a pore size of 0.7 microns and are binder free. They are used in Zero-Headspace Extractor Vessels for determining the mobility of semi-volatiles. Filters should be acid washed prior to use with 1N nitric acid followed by three consecutive rinses with deionized water. A minimum of 1 liter per rinse is recommended.
