[ 4 ] [ 1 ] The Bunsen burner , combined with a prism (filtering the color interference of contaminants ), led to the creation of the spectroscope , capable of ...
A laboratory tripod is most commonly used in middle and high schools for basic heating experiments. [2] However, tripods and bunsen burners have been made obsolete by hot plates, which are considered to be safer since there is no direct contact with the flame.

It is used when laboratory work requires a hotter flame than one attainable using a Bunsen burner, or when a flame of larger diameter is desired, such as when working with inoculation loop needing sterilization or in some glassblowing operations. The burner was introduced by French chemist Georges Méker in an article published in 1905. [1]

A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes. The triangle is usually supported on a tripod or iron ring.
