PYREX 32940-50F High Form Gooch Crucible with Fine Fritted Disc – 50 mL

The PYREX 32940-50F High Form Gooch Crucible with Fine Fritted Disc is a premium-quality, reusable laboratory filtration crucible designed for fine-particle filtration, gravimetric analysis, precipitate collection and analytical sample preparation. Manufactured by Corning from durable borosilicate glass, this high-form Gooch crucible features a permanently integrated fine-porosity fritted glass disc that provides an effective filtration surface for retaining suitable fine precipitates without the need for conventional filter paper. The crucible has a nominal capacity of 50 mL and incorporates a 40 mm diameter fritted glass disc with a pore size range of 4–5.5 micrometres. Its cylindrical high-form design makes it particularly suitable for analytical procedures where precipitates must be collected, dried and weighed to constant mass. The PYREX 32940-50F is designed for drying precipitates at approximately 110°C and can be used at higher temperatures with appropriate electric furnace equipment and careful temperature control. Its excellent chemical resistance, transparent construction and reusable design make it suitable for chemical analysis laboratories, pharmaceutical quality-control facilities, universities, industrial testing laboratories and scientific research institutions.
