PYREX 32940-50C High Form Gooch Crucible with Coarse Fritted Disc – 50 mL

The PYREX 32940-50C High Form Gooch Crucible with Coarse 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 incorporates a permanently fitted coarse-porosity fritted glass disc that provides a filtration surface without requiring conventional filter paper for suitable applications. The crucible has a nominal capacity of 50 mL and features a 40 mm diameter coarse fritted disc with a pore size range of 40–60 micrometres. Its high-form cylindrical design supports the collection, drying and weighing of solid precipitates during quantitative chemical analysis. The PYREX 32940-50C is particularly suitable for analytical procedures in which collected precipitates must be dried to constant weight at approximately 110°C. The crucible may also be used at higher temperatures in appropriate electric furnace equipment, provided rapid temperature changes are avoided. Its transparent construction, chemical resistance and reusable design make it suitable for chemical laboratories, pharmaceutical quality-control facilities, research institutions, universities and industrial testing laboratories.
