Grade A Porcelain Crucible Lids – Squat Form 15ml (Pack of 10)

These Grade A Porcelain Crucible Lids are specifically designed to fit squat‑form 15ml porcelain crucibles, providing secure coverage and improved control during high‑temperature experiments. Supplied as a pack of 10, they are produced under a certified ISO 9001:2000 production quality management system, ensuring consistent quality and dependable performance in educational and laboratory environments.

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

When used with compatible squat‑form crucibles, these lids help to reduce heat loss, limit contamination, and minimise spitting or sample loss during strong heating. This supports safer working conditions and improves the accuracy and consistency of experimental results.
