Specialty glass microfiber media have unique material properties that may include: binderless, acrylic binder, organic binder, laminated, double laminated and hydrophobic. They also have efficiencies that range from medium to ultra high. Specific applications are listed in the specialty glass microfiber grade descriptions below.
MultiDensity Filter Discs, Standard and Thinner Versions
Using a newly developed production method Tremont produces MultiDensity™ filters with a choice of final retention stages of <0.5μm to 2.7μm (the same as Tremont's binderless glass microfiber line of products). A thinner MultiDensity™ Filter is now offered that offers faster flow rates. The unique MultiDensity™ filter has a robust prefilter built-in which captures particulate from >300μm and binds typically difficult to filter substances without clogging such as:
Lipids (natural oils and waxes)
Petrochemical oils, tars
Irregularly granular matter
Viscous suspensions and slurries
Manifold vacuum filtration
Short path extraction methods
Positive pressure devices
Structured devices such as inline filters & capsules
The flow and drainage rate is exceptionally rapid via its highly irregular surface formation which has high and low points that aid in the reduction of 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 similarly to glass floss. In standing solutions the prefilter side resists compaction causing surface plugging found in other common filter configurations.
The filter is free of binders, glues and resins which ensure a higher purity filtrate. These filters demonstrate very low extractables. This filter replaces 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.
The 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.
The final filtration stage is available in the same porosity range of IW Tremont's binderless glass line, including the newly introduced Grade A-83 Nano-Scale filter.
