Glass Ignition Tubes (Fusion Tube) – Soft Glass, Pack of 100

Glass Ignition Tubes (Fusion Tube) – Soft Glass, Pack of 100

The Apex Labs Glass Ignition Tubes (Fusion Tubes) are vital, high-volume laboratory consumables engineered for performing sodium fusion tests and intensive microscale heating experiments in chemistry laboratories. Manufactured from choice soft glass (soda-lime composition), these tubes feature a specialized thin-walled architecture that guarantees exceptionally rapid and uniform heat transfer rates. Designed deliberately to withstand concentrated flame exposure up to the point of softening or melting during chemical profiling, this bulk pack of 100 tubes serves as the definitive standard for qualitative organic analysis workflows.

Performance Highlights

• Rapid Thermodynamic Transfer: Specially engineered thin-walled profiles allow sample materials inside to reach extreme fusion temperatures almost instantly over a standard Bunsen flame.
• Optimized Soft Glass Composition: Soda-lime glass formulation is deliberately selected for single-use thermal destruction, allowing clean tube breaking into distilled water without releasing problematic glass shards.
• Strict Geometric Uniformity: Standardized 40mm x 5mm manufacturing profiles ensure repeatable, predictable heating kinetics across all 100 elements in the batch.
• Localized Heat Resilience: Carefully calibrated to withstand extreme heating stresses before softening, providing a safer user window during hazardous fusion extractions.

Primary Sector Applications

• Sodium Fusion Test (Lassaigne’s Test): The foundational laboratory technique for identifying the organic presence of Nitrogen, Sulfur, and Halogen heteroatoms.
• Qualitative Micro-Heating: Small-scale dry heating tests used to observe physical sublimation, gas evolutions, or chemical color transitions.
• Crude Melting Point Screenings: Economical and simple alternative vessel setups for basic thermal testing of solid crystal substances.
• Educational Chemistry Kits: A fundamental high-volume standard component for training student groups across academic science institutions and board curricula.
