Laboratory burners — from the classic Bunsen burner to modern micro burners — are essential for sterilization, heating, and aseptic techniques in microbiology and chemistry labs. Choosing between gas burners, alcohol lamps, and electric micro burners involves trade-offs in temperature, safety, and convenience.
Types of Lab Burners
| Type | Fuel Source | Max Temp | Best For |
|---|---|---|---|
| Bunsen Burner | Natural gas/LPG | ~1570°C | General heating, sterilization, bending glass |
| Tirrill Burner | Natural gas/LPG | ~1800°C | High-temperature work, glass blowing |
| Alcohol Lamp | Ethanol/Methanol | ~600°C | Microbiology aseptic technique |
| Micro Burner (Electric) | Electricity | ~900°C | Biosafety cabinets, sterile loops |
Safety Tips for Lab Burners
- Ventilation — always use gas burners in well-ventilated areas or fume hoods
- Gas connection — check hoses and connections for leaks before each use
- Flame adjustment — a blue flame indicates complete combustion; a yellow flame produces soot and is less efficient
- Distance — keep flammable materials at least 30 cm from the burner
- Supervision — never leave an active burner unattended
- Shut-off — turn off the gas supply at the source after use
Micro Burners for Modern Labs
For labs using biosafety cabinets where open flames are not recommended, electric micro burners provide a safer alternative. They reach sterilization temperatures within seconds and switch off automatically — ideal for loop sterilization in BSL-2 facilities.
JWRESEARCH lab burners are available through JW RESEARCH SUPPLY Singapore, including Bunsen burners, alcohol lamps, and electric micro burners suitable for all laboratory environments.
