LabExact Glass Nano Fiber Filter Membrane, 2.5 cm, Binderless, Grade A-83 (100/Pack)

Glass microfiber filters offered in this product range from IW Tremont are produced from 100% borosilicate glass microfiber without the use of binders or strengthening agents. These filters offer many advantages in a wide range of analytical applications. The fibers used to manufacture these depth filters are smooth and uniform. This permits their characteristically high flow rates while allowing retention of exceptionally small particles and high load capacity. These characteristics are particularly important in applications involving high concentrations of particulate or gelatinous substances. In choosing the appropriate filter for a specific application, careful consideration should be given to the physical form and concentration of the material to be captured by the filter. Glass Microfiber Characteristics include:

Fastest flow rate
High load capacity
Retention of particles to sub-micron size
Temperature range up to 500°C
Use in liquid and gaseous filtration
Inert fiber composition
Free of binders or additives

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. 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.
