PYREX® Gooch Filtering Crucibles, High Form
PYREX® high form glass gooch filtering crucibles fritted discs for filtering applications and are available with different porosities from fine to medium to coarse. These glass filtering crucibles are particularly adapted to analytical work where precipitates are dried to constant weight at 110°C. They are also suitable for higher temperatures, in which case it is advisable to heat in an electric furnace. PYREX® glass gooch filtering crucibles should not be subject to sudden temperature changes. In order to avoid strain, they should not be removed from the furnace until the temperature has dropped to 250°C. PYREX® filter tubes (See Item Nos. COR-9480-20 & -25) are often used on the bottom of these crucibles to collect the filtrate.
