A Glass Bunsen Burner (Spirit Lamp) is a self-contained heating tool used as a portable alternative to gas-powered Bunsen burners. It is primarily used for light-duty heating, flame sterilization of microbiology tools, and laboratory demonstrations where natural gas is unavailable.
Core Components.
- Reservoir: A glass container, typically holding 60mL to 150mL, that stores the liquid fuel.
- Wick: A cotton or ceramic fiber cord that draws fuel upward through capillary action.
- Cap/Snuffer: A glass or metal cover used to extinguish the flame by cutting off the oxygen supply.
Recommended Fuels
For a clean, soot-free flame, use alcohols with 90% concentration or higher:
- Denatured Alcohol (Methylated Spirits): The most common and cost-effective choice.
- Ethanol: Produces the cleanest flame and is preferred for safety in some laboratory settings.
- Isopropanol (Isopropyl Alcohol): Can be used but may produce more soot if the concentration is below 90%

Safety & Maintenance
- Filling: Only fill the reservoir between 1/4 and 2/3 full. Filling it more can cause spills, while filling it less can lead to hazardous vapor buildup.
- Extinguishing: Always use the snuffer cap. Never blow on the flame, as this can cause hot alcohol to splash.
- Storage: If the lamp won't be used for several hours, return the fuel to its original container. The caps are rarely airtight, leading to fuel evaporation.
- Inspection: Always check for cracks or chips in the glass before lighting; heat can cause a damaged vessel to shatter.
