The Bunsen tripod , named after the German chemist Robert Wilhelm Bunsen , (also laboratory tripod ) is an aid in the chemical laboratory .

In its basic form it consists of a heavy metal base plate of approx. 10 cm × 25 cm and a round metal rod of 10 to 12 mm in diameter of various lengths screwed in vertically on one narrow side. Additional aids, including vessels, burettes, etc., can be attached to this rod in any position and height using clamps of different designs .

Bunsen tripods can also be combined into several (with rods and clamps) for extensive assemblies.

Although they are available, Bunsen tripods with round or barrel-shaped feet are rarely used because of their poor stability.

A cooking ring on a Bunsen tripod often replaces the rigid tripod .
