| TYPES OF BUNSEN BURNERS | Standard Bunsen Burner: Features a simple adjustable air collar at the base. It allows users to switch between a cool, visible yellow safety flame and a hotter blue heating flame. Widely used in secondary schools and general science education. Micro Bunsen Burner: A scaled-down version used when there are strict space or height restrictions in the workspace. It is ideal for delicate, low-intensity heating tasks. Tirrill Burner: Similar to a standard Bunsen burner, but includes both an adjustable air collar and a needle valve to precisely control the gas flow. This allows for fine-tuning of the air-to-gas ratio to achieve hotter, exact flame temperatures. Meker Burner: Designed for applications that require a much hotter and wider flame spread. It features a wider tube and is capped with a wire grid, which divides the flame into an array of smaller, evenly heated blue cones that can reach temperatures up to 1,200 °C. Teclu Burner: Features a conical base and a screw nut that regulates air intake. It allows for better air-to-gas mixing, resulting in a hotter flame than a conventional Bunsen burner. Flame Stabilised Burner: Designed for advanced airflow and reduced turbulence, producing a highly consistent heating zone. It is the preferred choice for microbiology and sterilization environments |
| WHAT ARE BUNSEN BURNERS USED FOR? | Heating: Used to boil, evaporate, or melt substances in beakers, test tubes, or crucibles. It is also used to speed up specific chemical reactions. Sterilisation: The intense heat (especially from a blue flame) quickly sterilises metal lab tools—such as inoculating loops, scalpels, and forceps—to prevent contamination. Flame Tests: By holding specific metal salts in the flame, scientists can identify elements based on the characteristic color the metal emits when burned. Glass/Metal Modification: The open flame is used to bend, pull, or polish glass pipettes and rods. |
