To separate a mixture you can use distillation amongst others. The distillation bridge is thereby the way between the two pots. In the one pot there is the mixture to be separated. Through heating, a gas forms which is lead through the bridge. At the end of the bridge the gas phase is condensed again and drips in a round flask. As a rule, the bridge is cooled by return flow. In addition, there is often a thermometer for controlling the temperature on the distillation bridge.
