MultiDensity™ Disk, 0.7micron final retention, 4.7cm dia, 10 per pack - MD-070-2006MultiDensity™ filter disks are a 100% borosilicate binderless glass microfiber filter which demonstrates several layers of density along with a unique surface formation that speeds and optimizes filtration. This unique product bridges the gap between macro and micro analytical filtration. MultiDensity™Filters replace multi pre-filtration stage products in applications where a series of prefilters are used to prepare sample prior to membrane filtration, saving time and reducing variability in extract signature upon analysis methods. This filter media is available with a choice of final retention stage ranging from <0.5?m nano scale to 2.7?m (the same as Tremont’s binderless glass microfiber line of products).
The unique filter has a robust and built-in prefilter which captures particulate from >300?m and binds typically difficult to filter substances without clogging such as lipids (natural oils and waxes), petrochemical oils, tars, cellular matter, proteins, irregularly granular matter and viscous suspensions and slurries.
The flow and drainage rate is exceptionally rapid via its highly irregular surface formation with high and low points that reduce surface loading. The unique fibers which sit on the outermost surface of the pre-filter side are designed to extend up and add further prefiltration structure, similar to glass floss. In standing solutions, the prefilter side resists compaction causing surface plugging found in other common filter configurations. The filter is optimized to meet the extreme demands of high fluidic volume in manifold vacuum filtration, short path extraction methods, Positive pressure devices and structured devices such as inline filters & capsules.
The filter is free of binders, glues and resins which ensure a higher purity filtrate. Filters demonstrate very low extractable and borosilicate glass is highly resistive to aggressive solvents, acids and base with a usable range of 0-14pH and a wide effective temperature range of -200 to 500 °C.
