High-Temperature Laboratory Ignition Tube
An ignition tube is a heavy-walled, hard glass vessel designed to withstand direct flame from a Bunsen burner, ideal for heating small quantities of substances during combustion or analysis. Each tube is typically rimless for ease of use, heat resistant up to around 500 °C during continuous exposure, and briefly tolerating up to 600 °C. 

Compact, Precision Heating for Chemical Testing
These compact ignition tubes allow practitioners to carefully observe reactions and perform tests such as sodium fusion with precision—handling only minimal sample amounts while reducing waste and focusing heat effectively. The thick walls ensure durability under intense localized heating, avoiding deformation or flash breakage during high-temperature experiments.

Disposable or Reusable Options in Borosilicate Glass
Ignition tubes are available both as disposable versions—ideal for quick, contamination-free experiments—and as reusable variants constructed from borosilicate like PYREX®, offering resistance to thermal shock and chemical corrosion for frequent usage. 

Essential Tool for Education and Lab Work
These tubes are widely used in educational settings—from school science labs to advanced research—for practical demonstrations or analytical procedures. Their simplicity, resilience, and suitability for high heat make them an indispensable tool in chemistry toolkits.
