Spirit Lamp for Chemistry Lab – Alcohol Burner
The Spirit Lamp is a small, portable laboratory burner used for gentle heating, certain flame-test procedures, and suitable for sterilization work. Supplied by Elmo Agencies, a trusted scientific manufacturer in Ambala, it is suitable for school, college, chemistry, and biology laboratories where a simple heat source is required.
A Spirit Lamp consists of a fuel reservoir, cotton wick, wick holder, and fitted cap. It uses a compatible alcohol-based fuel, commonly methylated spirit or denatured alcohol, which is drawn through the wick and burned to produce a relatively small flame.
Unlike a Bunsen burner, a spirit lamp does not require a piped gas supply, making it a convenient portable heating option. Its flame is generally less powerful and less adjustable than that of a Bunsen burner.
Parts of a Spirit Lamp
| Part | Function |
|---|---|
| Reservoir | Holds the compatible liquid fuel |
| Wick | Draws fuel upward through capillary action |
| Wick Holder | Holds and positions the wick |
| Cap | Extinguishes the flame and helps limit fuel evaporation |
| Base | Provides support and stability on the laboratory bench |
What Fuel Is Used?
Spirit lamps are generally designed for a compatible alcohol-based fuel, such as methylated spirit or denatured alcohol, according to the product instructions.
Petrol, kerosene, diesel, or other unsuitable petroleum fuels should never be used, as they can produce hazardous flames, fumes, and operating conditions.
Uses of a Spirit Lamp
- Gentle heating of small quantities of liquids
- Heating suitable test tubes and laboratory vessels
- Certain flame-test procedures
- Suitable sterilization procedures
- Educational chemistry demonstrations
- Softening suitable glass tubing
- Basic laboratory heating applications
How It Works
The wick draws the liquid fuel upward through capillary action. When the exposed wick is ignited, the fuel vapour burns and produces the flame.
The flame can be extinguished by placing the fitted cap over the wick, cutting off the oxygen required for combustion.
Spirit Lamp vs Bunsen Burner
| Feature | Spirit Lamp | Bunsen Burner |
|---|---|---|
| Fuel | Liquid alcohol-based fuel | Laboratory gas |
| Gas connection | Not required | Usually required |
| Portability | Highly portable | Less portable |
| Heating | Gentle | Higher-temperature heating |
| Flame control | Limited | More adjustable |
| Typical use | Gentle heating and demonstrations | Strong laboratory heating |
Safety Precautions
- Use only the fuel specified for the lamp.
- Never refill a lit or warm lamp.
- Wipe away spilled fuel before lighting.
- Keep flammable liquid away from the flame.
- Never leave a burning lamp unattended.
- Alcohol flames can be difficult to see in bright conditions.
- Extinguish the flame using the cap rather than blowing on it.
- Allow the lamp to cool completely before refilling.
Conclusion
The Spirit Lamp by Elmo Agencies is a compact and portable laboratory burner designed for gentle heating and suitable for educational laboratory procedures. Its wick-and-reservoir design makes it useful for chemistry and biology practicals, demonstrations, and applications where a simple alcohol flame is appropriate.
