Faster flow, higher retention than cellulose filters Used as prefilters and for gravimetric analyses
Suitable for many corrosive applications
Low hygroscopicity Chemically and biologically inert, with no organic binders Offer higher retention efficiency of fine particles (<3μm in size) Resist clogging for greater loading capacity than cellulose paper filters Autoclavable and usable to 500°C (932°F) Filters should be used flat: folding will break the glass fibers
