Glass fiber filters are made of 100 % borosilicate microfibers and are characterized above all by their inert behavior towards acids (with the exception of hydrofluoric acid), moderately concentrated alkalis and high temperatures. Glass fiber filters are fast filtering and have a high retention capacity of even the finest particles in the subµ range. Due to their high retention capacity, glass fiber filters can be used for larger volumes compared to paper filters, as the filtration speed decreases less with increasing particle load. Glass fibre filters from established manufacturers like Pall, Whatman, Sartorius, etc are available here.
The Schleicher & Schuell brand is part of the Whatman group but their filters are graded differently. The following table should simplify the task of comparing the different glass fibre media for your filtration needs.
