CHF-50-20 Porcelain Crucibles with Lids Pack of 20 – High-Form 50 mL Laboratory Crucibles for Heating and Combustion Experiments

High-Form Porcelain Crucibles with Lids are durable, heat-resistant vessels designed for laboratory heating, combustion, and analytical experiments. Each crucible holds 50 mL and features uniform, dense porcelain construction that resists cracking and chemical attack. Glazed pieces withstand temperatures up to 1050 °C, while unglazed pieces can reach 1350 °C under proper use. These crucibles are perfect for ash content tests, dehydration reactions, and melting-point demonstrations, making them a valuable addition to chemistry classrooms and professional labs alike. Sold as a pack of 20.
