PYREX 32940-30F High Form Gooch Crucible with Fine Fritted Disc – 30 mL

The PYREX 32940-30F High Form Gooch Crucible with Fine Fritted Disc is a high-quality, reusable laboratory filtration crucible designed for gravimetric analysis, precipitate collection, filtration and sample drying in analytical laboratories. Manufactured by Corning from durable laboratory-grade borosilicate glass, this crucible features a permanently integrated fine-porosity fritted glass disc that provides a filtration surface for retaining suitable fine precipitates without requiring 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 4–5.5 micrometres. Its high-form cylindrical design is particularly suitable for analytical procedures requiring precipitates to be collected, dried and weighed to constant mass. The PYREX 32940-30F is designed for drying precipitates at approximately 110°C and can withstand higher temperatures when suitable laboratory heating equipment is used. Its reusable construction and chemical resistance make it suitable for chemical analysis laboratories, pharmaceutical quality-control facilities, research institutions, universities and industrial testing laboratories.
