Grade A Porcelain Crucible Lids – Squat Form 50ml (Pack of 10)

These Grade A Porcelain Crucible Lids are precision‑manufactured to fit squat‑form 50ml porcelain crucibles, providing secure coverage and improved safety during high‑temperature laboratory experiments. Supplied as a pack of 10, they are produced under a certified ISO 9001:2000 production quality management system, ensuring consistent quality, durability, and reliable performance in school and laboratory environments.

Manufactured from premium laboratory porcelain, these crucible lids are renowned for their excellent thermal and chemical resistance. Their robust construction enables them to withstand sustained temperatures of 1100°C+ under suitable conditions, making them ideal for repeated use in school science laboratories, prep rooms, and controlled classroom demonstrations.

When used with compatible squat‑form crucibles, these lids help to reduce heat loss, minimise contamination, and prevent spitting or sample loss during strong heating. This improves safety for students and technicians while supporting accurate and consistent experimental results.
