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.

Advantec Quantitative Ashless Filter Papers are made from the highest quality alpha cotton cellulose. One critical step in the manufacturing process of these filter papers is acid washing. All grades are double acid washed in hydrochloric then hydrofluoric acid to reduce levels of SiO2, CaO, and Fe2O3. Following the acid wash, all papers are rinsed in ultrapure water to neutralize. Grade No. 4A Hardened is further treated with nitric acid. Following the acid wash, all papers are rinsed in ultrapure water to neutralize. Ash Content: 0.01% (except Grade No. 4A is 0.025%). Grade No. 3 Medium retention, fast flow rate paper with good chemical resistance and wet strength. Recommended for analysis of soils, fertilizers, cement, and minerals. Nominal Retention: 5 µm. Grade No. 5A Retains coarse and gelatinous ppt with high flow rates. Filter hydroxides, metalic aerosols, environmetnal monitoring, and determine silica content in steel. Nominal Retention: 7 µm. Grade No. 5B Retains medium size ppt such as CaCo3, PbSO4, AgCl. General purpose paper. Nominal Retention: 4 µm. Grade No. 5C High retention efficiency collecting fine ppt such as BaSO4 with slow flow rate. Gravimetric analysis and collecting particles that tend toward colloidal dispersion. Nominal Retention: 1 µm. Grade No. 6 Retains medium-fine particulates. Use for precision analysis of trace and precious metals, beverages, water. Nominal Retention: 3 µm. Grade No. 7 Highest purity paper for medium particulates. Fast flow rate. Recommended for precise gravimetric analysis of minute trace and precious metals. Nominal Retention: 4 µm. Grade No. 4A Hardened, smooth low ash paper with superior wet strength. Retains fine crystalline ppt with slow flow rate. Suitable for Buchner filtrations, high pressure, high chemical and pH resistance. Nominal Retention: 1 µm. Please Note: ALL Advantec items have a maximum 48 hour cancellation window.

Sterile Mixed Cellulose Esters (MCE) Membrane Filters - White •Available pore sizes: 0.20µm, 0.45µm, 0.65µm, 0.80µm, 1.0µm, 3.0µm •Color: White •Surface: Gridded or Plain, and with or without Hydrophobic Edge (HE) •Packaging: Individually wrapped or multipack, and with or without absorbent pad. Pleated band for dispensers available. Mixed Cellulose Esters (MCE) membrane is a general purpose filter used in many applications for the microbiological examination of water, wastewater, pharmaceuticals, food, and beverages and air monitoring. MCE membranes offer high recovery rates and superior flow rates. Advantec MCE membranes are high purity and Triton-free. Contrasting grid lines facilitate counting colonies and are tested to assure freedom from grid line inhibition. 3.1mm squares represent 1/100 of the filtration area of a 47mm diameter filter (9.6cm2). Membranes are sterilized by ethylene oxide (EtO) gas and are available individually wrapped or in 10-pack envelopes. Membrane specifications and lot number are printed on clear cover of each filter. Advantec's continuous pleated band packaging is compatible with various membrane dispensers. Advantec membranes were developed and are manufactured to comply with the ASTM and the Standard Methods for the Examination of Water and Wastewater. Quality control tests are performed on each lot and QA Certificates are available. Please Note: ALL Advantec items have a maximum 48 hour cancellation window.
