PYREX 32940-30M High Form Gooch Crucible with Medium Fritted Disc – 30 mL

The PYREX 32940-30M High Form Gooch Crucible with Medium Fritted Disc is a premium-quality, reusable laboratory filtration crucible designed for gravimetric analysis, precipitate collection, filtration and sample drying in analytical and research laboratories. Manufactured by Corning from durable borosilicate glass, this high-form Gooch crucible features an integrated medium-porosity fritted glass disc that provides a reliable filtration surface for separating suitable solid particles from liquids without conventional filter paper. The crucible has a nominal capacity of 30 mL and incorporates a 30 mm diameter fritted glass disc with a pore size range of 10–15 micrometres. Its cylindrical high-form design is particularly suitable for analytical procedures requiring precipitates to be collected, dried and weighed to constant mass. The PYREX 32940-30M is designed for drying precipitates at approximately 110°C. It is also suitable for higher-temperature procedures using appropriate electric furnace equipment, provided thermal shock is avoided. Its chemical resistance, reusable glass construction and integrated filtration medium make it suitable for chemical analysis laboratories, pharmaceutical quality-control facilities, universities, industrial testing laboratories and research institutions.
