Product Description
This Fusion Tube is a laboratory ignition tube used for sodium fusion, also known as Lassaigne’s test, a qualitative analysis technique for detecting nitrogen, sulfur, and halogens in organic compounds. It is manufactured from heat-resistant glass to withstand the thermal conditions of the fusion process. Sodium fusion involves heating organic compounds with metallic sodium, which is highly reactive with water and moisture and poses a fire hazard — this procedure should only be performed by trained personnel using appropriate safety precautions (fume hood, eye protection, and dry conditions), and the fusion tube should not be exposed to moisture during use.
Specifications

Applications / Uses
- Sodium fusion (Lassaigne’s test) qualitative analysis
- Detecting nitrogen, sulfur, and halogens in organic compounds
- Chemistry laboratory qualitative analysis procedures
- Educational demonstrations of organic compound testing (supervised, trained use only)
Care & Maintenance
- Handle metallic sodium only under trained supervision — it reacts violently with water/moisture and poses a fire hazard
- Perform sodium fusion in a fume hood with appropriate eye and hand protection
- Inspect the glass tube for cracks before each use to prevent failure under heat
- Store in a dry environment away from moisture
