Grade A Porcelain Crucible Lids – Squat Form 11ml (Pack of 10)

These Grade A Porcelain Crucible Lids are designed specifically to fit squat‑form 11ml porcelain crucibles, providing secure coverage and improved control during high‑temperature experiments. Supplied as a pack of 10, they are manufactured under a certified ISO 9001:2000 production quality management system, ensuring consistent performance and reliability for educational and laboratory use.

Manufactured from premium laboratory porcelain, these crucible lids offer excellent thermal and chemical resistance. Their robust construction allows them to withstand temperatures of 1100°C+ under suitable conditions, making them ideal for repeated use in school laboratories, prep rooms, and controlled demonstration environments.

When used with compatible squat‑form crucibles, these lids help to reduce heat loss, minimise contamination, and prevent spitting or material loss during strong heating. This supports more accurate experimental outcomes while promoting safe laboratory practice.
