Porcelain Crucibles Grade A – 11ml, Without Lid (Pack of 10) [Model 8042]

The Grade A Porcelain Crucibles – 11ml (without lid) are premium laboratory vessels designed for high‑temperature heating, ignition, and thermal decomposition of solid samples. Manufactured using high‑purity laboratory porcelain developed through many years of specialised research and expertise, these crucibles provide excellent reliability for educational and professional laboratory use.

Produced under a certified ISO 9001:2000 quality management system, these crucibles are made exclusively from the highest‑grade raw materials. The porcelain structure contains well‑developed mullite crystals, which enhance the material’s softening point, mechanical strength, and resistance to chemical attack. A low coefficient of thermal expansion enables the crucibles to withstand severe thermal shock during repeated heating and cooling cycles.

Featuring a practical 11ml capacity and a stable squat form design, these crucibles are ideal for controlled heating and ignition of small samples. The glazed porcelain surface allows use at temperatures in excess of 1100°C under suitable laboratory conditions, making them suitable for Bunsen burners, hot plates, and muffle furnaces.
