Whatman glass microfiber filters are manufactured from 100% borosilicated glass and are chemically inert and completely binder free. These depth filters combine fast flow rates with high loading capacity and the retention of very fine particles, exlending into the submicron range.
Glass microfiber filters can be used of lemperafures up to 500℃ and are ideal for use in applications involving the filtration of hot gases and for gravimetric analysis of volatile materials where ignition is involved.
Whatman glass microfiber filters have a fine capillary structure and can absorb significanfly larger quantities of water than an equivaient cellulose filter, making them suilable for spot tests and liquid scinfillation counting methods. The filters can also be made completely transparent for subsequent microscopic examination.
