CORNING 32940-30F
These PYREX® high form crucibles have varying diameter porosity fritted discs. They 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. 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 (No. 9480) are often used on the bottom
of these crucibles to collect the filtrate.
