- Ignition tube
An ignition tube is a piece of
laboratoryequipment. It is a laboratory tubeused much in the same way as a boiling tubeexcept not being as large and thick-walled. It is primarily used to hold small quantities of substances which are undergoing direct heating by a Bunsen burneror other heat source.
Ignition tubes are used, e.g. in the
sodium fusion test.
Ignition tubes are often difficult to clean due to the small bore. When used to heat substances strongly, some char may stick to the walls as well. They are usually disposable.
