NanoGF™ Binderless Grade A-83 glass fiber filter media, 0.5micron retention, 4.25cm diameter - 100/pk - A83-4250Grade A83 Nano-scale glass microfiber has the loading capacity of a binderless glass microfiber filter with the tightly regulated pore size of a microfiltration membrane. This specialty grade has a particle retention of 0.5µm. A83 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. With >85% of the fiber content between 300nm -1000nm, this material is truly one of the highest surface area binderless glass microfiber products on the market today.
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. The smooth sheath of the glass fiber allows tight consolidation into a highly retentive filter mat. This grade is highly consistent from lot to lot and similarly uniform in thickness and mass to other well-known Tremont grades such as Grade C or E. High protein affinity and highly washable for separation recovery. Excellent as a pre-filter for micro-porous membranes such as polymeric structures, track etched polycarbonates and other monolithic membrane materials. Much wider degree of heat tolerance than any other polymeric membrane. Usable temperature to 500° C. Chemically stable in presence of all acids with exception of hydrofluoric acid.
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.
