Porcelain Crucibles Grade A – 6ml, Without Lid (Pack of 10) [Model 8041]

The Grade A Porcelain Crucibles (6ml, without lid) are high‑quality laboratory vessels designed for strong heating, ignition, and thermal decomposition of small samples. Manufactured from premium laboratory porcelain using years of specialised research and production expertise, these crucibles deliver exceptional performance in both educational and professional laboratory environments.

Produced under a certified ISO 9001:2000 quality management system, these crucibles are manufactured using only the highest‑grade raw materials. The porcelain structure contains well‑developed mullite crystals, which provide outstanding chemical resistance, high mechanical strength, and a low coefficient of thermal expansion. This ensures excellent resistance to thermal shock and allows the crucibles to withstand repeated heating and cooling cycles.

With a 6ml capacity and a practical squat form design, these crucibles are ideal for controlled heating of small quantities of material. The glazed porcelain surface permits use at temperatures exceeding 1100°C under suitable conditions, making them suitable for use over Bunsen burners, hot plates, or in laboratory furnaces.
