These 15mL PYREX low form crucibles have 20mm diameter medium porosity (10 to 15um) fritted discs. They are particularly adapted to analytical work where precipitates are dried to constant weight at 110C. 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 250C. PYREX filter tubes (No. 9480) are often used on the bottom of these crucibles to collect the filtrate.
