Porcelain Crucibles Grade A – 15ml, Without Lid (Pack of 10) [Model 8043]

The Grade A Porcelain Crucibles – 15ml (without lid) are high‑performance laboratory vessels designed for strong heating, ignition, and thermal decomposition of solid samples. Manufactured from premium laboratory porcelain, these crucibles are the result of many years of specialised research and production expertise, delivering outstanding reliability for educational and laboratory environments.

Produced under a certified ISO 9001:2000 quality management system, these crucibles are made exclusively from the highest‑grade raw materials. Their exceptional performance comes from well‑developed mullite crystals within the porcelain structure, which significantly increase the softening point while providing high mechanical strength and a low coefficient of thermal expansion. This allows the crucibles to withstand severe thermal shock during repeated heating and cooling cycles.

With a practical 15ml capacity and a stable squat form design, these crucibles are ideal for controlled, high‑temperature work involving small quantities of material. The glazed porcelain surface enables use at temperatures exceeding 1100°C under suitable conditions, making them suitable for Bunsen burners, hot plates, and laboratory furnaces.
