Description
The silica crucible (without lid) from Osmosis Scientific is a laboratory-grade vessel crafted from high-purity fused silica, designed to meet the rigorous demands of high-temperature lab processes. Silica is especially valued in scientific settings due to its extremely low thermal expansion coefficient, which imparts exceptional resistance to thermal shock — a key advantage during rapid temperature changes and repeated heating cycles.
These crucibles deliver outstanding chemical inertness, meaning they won’t react with most substances encountered during sample preparation. This makes them ideal for applications such as ashing organic materials, drying samples, thermal decomposition, fusion, and other heating workflows where purity and material stability are essential.
The open top design (without lid) enables easy access to samples and straightforward retrieval following thermal processing. The smooth fused silica surface also simplifies cleaning and sample transfer, reducing contamination risks and saving lab time.

Frequently Asked Questions (FAQs)
Yes. The low thermal expansion of silica allows crucibles to tolerate rapid heating and cooling with minimal cracking.
These crucibles are suitable for elevated laboratory temperatures — typically up to and beyond standard ceramic limits, depending on application conditions.
A range of ml sizes is offered to match different experimental and processing needs.
