Depth filtration glass micro fiber GRADE A-E - Fine porosity and fast flow rate, with a 1.0 µm size particle retention. Binderless borosilicate glass microfiber. DOP efficiency is 99.98%. Primarily used in suspended solids and air monitoring. Particle retention: 1.00 µm Filtration speed: 15 seconds Thickness: 0.33 mm Basis weight: 60 g/m 2 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 pore structure that develops as the fibers overlap. The fibrous material within the filter is commonly glass micro fiber or polypropylene. In depth filters such as glass micro fiber, 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. 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 course particulate. Glass micro fiber filters are available without binders, making the inertmatrix an ideal medium to entra-sediment for further analysis and counting. Also, depth filtration media is commonly used as pre-filtration prior to surface filtration substrates such as membranes.

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 (9.6cm 2 ). 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. 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.

Nalgene filters have the Rapid-Flow multi-column membrane-support system. This proprietary system provides a uniform, consistent separation between touchpoints with the membrane, minimizing gap stress to maintain optimal flow. Polystyrene housing 90mm Supor®* machV PES membrane 90-mm diameter membranes for faster flow rates. Filters securely screw onto glass media bottles with 33- or 45-mm neck sizes. Allow direct flitration of liquid into sterile glass media bottles*. BLUE collar. Side-arm with quick-disconnect tubing adapter. Nalgene PES: The best choice for cell culture Polyethersulfone (PES) is the ultimate tissue culture membrane. It’s fast and clean. PES is low protein binding, so there is less chance of removing critical protein from your media. It is hydrophilic, so no external wetting agents or surfactants are needed, resulting in low extractables. And it is fast, so you spend less time waiting. WARNING! All NALGENE Filterware is for research use only, not for in vitro diagnosis or parenterals. *CAUTION: Use only sterile bottles designed for use with vacuum. Always use safety shield during vacuum procedures.
