Grade A Porcelain Crucibles – 25ml (Pack of 10, Without Lid)

These high‑quality Grade A Porcelain Crucibles are designed for reliable performance in educational and laboratory settings. Manufactured from premium laboratory porcelain, they are supplied as a pack of 10 squat‑form crucibles, each with a 25ml capacity and no lid. Produced under a certified ISO 9001:2000 quality management system, they offer consistent results and long‑term durability.

Jipo laboratory porcelain is the result of many years of research and specialist expertise and is globally recognised for its excellent chemical and thermal resistance. The exceptional performance of these crucibles is due to their well‑developed mullite crystal structure, which increases the softening point, provides high mechanical strength, and delivers a low coefficient of thermal expansion. This combination allows the crucibles to withstand rapid temperature changes and high thermal shock.

Manufactured using only the highest‑grade raw materials, these glazed porcelain crucibles are suitable for use at temperatures of up to 1100°C under appropriate conditions. While primarily intended for laboratory use, the high‑quality porcelain construction also makes them suitable for certain controlled kitchen and educational demonstration environments.
