Material Specs

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 void space structure that develops as the fibers overlap. The fibrous material within the filter is commonly glass microfiber, cellulose or polypropylene. In depth filters using glass microfiber, 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. All of the media described on this page are 100% borosilicate glass and free of binders.

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 coarse particulate. Glass microfiber filters without binders are an ideal medium to entrap sediment for further analysis and counting due to the inert matrix. Also, depth filtration media are commonly used for pre-filtration prior to surface filtration with substrates such as membranes.

GRADE A-83 - Imagine the loading capacity of a binderless glass microfiber filter with the tightly regulated pore size of a microfiltration membrane.

Now it's possible with Grade A83 NanoGF. This new grade has a particle retention of 0.5µm. It has >20x loading capacity of an equivalent porosity MCE or CN membrane and >15x the flow rate. Back pressure is nearly non-existent in comparison to surface membranes.

Chemically inert, pure binderless borosilicate glass with no sizing additives or other surfactants. Low background noise in LC/GC/MS and very low extractables in presence of aggressive solvents. There are many filter materials which make the claim of "nano-scale" fiber, but Grade A83 is tested by an independent laboratory using the latest in fiber analysis and SEM image quantification. With >85% of the fiber content between 300nm -100nm, this material is truly one of the highest surface area binderless glass microfiber products on the market today.

GRADE MD - Tightly regulated pore size of a microfiltration membrane with built in prefiltration.

This exciting new product is a 100% borosilicate binderless glass microfiber filter which demonstrates several layers of density along with a unique surface formation that speeds and optimizes filtration.
