Grade A Porcelain Crucible Lids – Squat Form 6ml (Pack of 10)

These Grade A Porcelain Crucible Lids are purpose‑designed to fit squat‑form 6ml porcelain crucibles, providing effective coverage and improved heat control during high‑temperature experiments. Supplied as a pack of 10, they are manufactured to exacting standards under a certified ISO 9001:2000 quality management system, ensuring dependable consistency and durability in educational and laboratory environments.

Made from premium laboratory porcelain, these crucible lids are engineered for excellent thermal and chemical resistance. Their robust construction enables them to withstand sustained temperatures of up to 1100°C+ under suitable conditions. This makes them ideal for repeated use in demanding settings such as school science laboratories, prep rooms, and controlled demonstration environments.

Designed to reduce heat loss and minimise contamination, these lids support more controlled reactions and improve experimental accuracy. When used alongside compatible crucibles, they also help protect students and technicians by limiting spitting or material loss during strong heating.
