Whatman offers two types of glass microfiber filters manufactured from 100% borosilicate glass:
binder-free glass microfiber that is chemically inert and binder glass microfiber.
These depth filters combine fast flow rates with high loading capacity and the retention of very fine particles, extending
into the sub-microrange. Glass microfiber filters can be used at temperatures up to 500° C and are ideal for use in
applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved.
