Let’s take a closer look at the key partsof aBunsen burner andtheir functions. 1. Base Thebase ofa Bunsenburner istypically made ofa sturdymetal, providingastablefoundationtopreventtippingduringuse.Itensures the burner remains in place while it’s being operated. 2. Gas Inlet The gas inlet is where the Bunsen burner connects to the gas supply, typicallythrougha rubberhose.The gasinletallows naturalgas or propanetoflowintotheburner.Properconnectioniscrucialfor ensuring the flame is ignited and controlled effectively. 3.

This adjustment is essential in controlling the oxygen supplytotheflame,which affectsitstemperatureandcolor. Themore air that enters the burner, the hotter and cleaner the flame will be. By rotatingthebarrel, youcanadjust thesize oftheair holes,influencing the flame’s characteristics. 5.
