Usage
Designed for use in academic research labs, industrial testing facilities, and educational workshops, this crucible excels in environments that require reliable performance at temperatures ranging from ambient to several hundred degrees Celsius. Typical applications include melting of low‑melting point metals, preparation of ceramic glazes, synthesis of inorganic compounds, and thermal analysis of material samples. The secure cover enables users to conduct reactions in an enclosed space, reducing the risk of spatter and preserving sample purity. Its compact dimensions make it ideal for bench‑top setups, glove boxes, and portable field kits where space is limited but performance cannot be compromised.

FAQ
What temperature range can this crucible safely handle?
The graphite material is rated for continuous use up to approximately 500 °C, making it suitable for most low‑ to medium‑temperature laboratory processes.
Is the cover compatible with other crucible sizes?
The cover is specifically molded to match the 40mm x 40mm dimensions of this model, ensuring a tight seal. It is not interchangeable with larger or smaller crucibles.
How should I clean the crucible after use?
Allow the crucible to cool completely, then gently brush away residues with a soft, non‑abrasive brush. For stubborn deposits, a mild solvent such as isopropyl alcohol can be used, followed by thorough rinsing and drying.
Can this crucible be used for reactive metals like aluminum?
Yes, the graphite surface is chemically inert to many metals, including aluminum, provided the reaction does not produce aggressive fluorides or chlorides that could attack the material.
What warranty does OTOOLWORLD provide?
OTOOLWORLD offers a one‑year limited warranty covering manufacturing defects. Contact the support team with your purchase details for assistance.
