GVS Filter Technology Part No. 1215540
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.

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.

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.
