It is called a griebon (pronounced jreeborn) or a tripod
Wire gauze can be used to support a container (such as a beaker or flask) during heating. When the Bunsen burner flame is beneath it, with a tripod, the wire gauze helps to spread the flame (and heat) out evenly over the container. It is frequently used in combination with an iron ring and ring stand with a Bunsen burner underneath it (see the Related Questions for more information about an iron ring, ring stand, and Bunsen burner & tripod). A clay triangle serves a similar purpose, except that a clay triangle is used for a crucible instead.
A Bunsen burner is typically used with a heat-resistant apparatus, such as a beaker, flask, or evaporating dish, placed over it to heat substances. A wire gauze may also be used to provide a stable surface and distribute heat evenly. In laboratory settings, a tripod or a stand may support the container above the flame.
They are used in practical experiments, particularly chemistry, to hold test tubes, burettes etc in position over something else such as a Bunsen burner or beaker.
Stand it on a heat-resistant pad... When not in use - turn the sleeve so that the yellow flame is visible... Keep all flammable items away from it.
An iron stand is a metal rod attached to a metal base. When an iron stand is used in a laboratory, beakers, Bunsen burners, pipettes, and a variety of other things a scientist may need in his work is placed on the iron stand.
A Bunsen burner typically stands on a heat-resistant mat or pad to protect the surface it is placed on from heat damage. Some laboratory benches may also have built-in heat-resistant surfaces for Bunsen burners to stand on.
A wire gauze is placed on a tripod stand on top of a Bunsen burner.
A Bunsen burner typically sits on a heat-resistant mat called a "laboratory tripod" or a "retort stand" with a wire gauze mat on top. This arrangement helps to protect the work surface from heat damage and provides a stable platform for the Bunsen burner.
In chemistry, a ring stand places a heated sample above the direct flame of a Bunsen burner.
ring stand ths it son
to hold objects above a Bunsen burner eg. a an evaporation basin :)
to put comtainers upon, especially when heating above a Bunsen burner
Used on top of a Bunsen burner so you can heat things. it normally has a gauze mat on it and you put a beaker, evaporating basin etc on top of it to heat.
In chemistry, a ring stand places a heated sample above the direct flame of a Bunsen burner.
The flame on a Bunsen Burner can be controlled by turning the thing on the bottom by the stand. When you turn it you are either letting the air in or cutting of the air to the flame, this will decide whether the flame will be blue or orange/yellow. Hope this helps! Ali
