PYREX 32940-50M High Form Gooch Crucible with Medium Fritted Disc – 50 mL

The PYREX 32940-50M 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 during analytical chemistry procedures. Manufactured by Corning from durable borosilicate glass, this high-form Gooch crucible incorporates a permanently integrated medium-porosity fritted glass disc that provides a reliable 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 medium fritted disc with a pore size range of 10–15 micrometres. This makes it suitable for retaining appropriately sized precipitates during analytical filtration and quantitative laboratory procedures. The PYREX 32940-50M is particularly suitable for laboratory applications requiring precipitates to be collected, dried and weighed to constant mass at approximately 110°C. Its chemical resistance, transparent construction and reusable design make it suitable for chemical laboratories, pharmaceutical quality-control facilities, universities, research institutions and industrial testing laboratories.
