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.
