Wire gauze or wire mesh is a gauze woven of metal wire, or very fine, gauze-like wire netting. Wire gauze is placed on the support ring that is attached to the retort stand between a burner and glassware , or is placed on a tripod to support beakers , flasks , or other glassware to protect it during heating.
A Bunsen burner placed atop a heatproof mat A heatproof mat An asbestos heatproof mat over a Teclu burner. A heatproof mat, also known as wire gauze or a gauze mat, is a piece of apparatus commonly used in tabletop lab experiments that involve moderate temperatures (for example, when a Bunsen burner is being used) to prevent damage to a work surface.

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 safer in modern reproductions of this experiment to use a borosilicate glass tube or, better still, one made of metal. Instead of heating the gauze with a flame, Rijke also tried electrical heating. Making the gauze with electrical resistance wire causes it to glow red when a sufficiently large current is passed. With the heat being ...
Several laboratory experiments are capable of producing relatively pure gas as an end product, and it may be useful to demonstrate the chemical identity of that gas. Burning splints or glowing splints can be used to identify whether a gas is flammable , whether it is oxidising , or whether it is chemically inert .
Structured packing. The term structured packing refers to a range of specially designed materials for use in absorption and distillation columns [1].Structured packings typically consist of thin corrugated metal plates or gauzes arranged in a way that force fluids to take complicated paths through the column, thereby creating a large surface area for contact between different phases.
The leather is very thin, maybe 0.4-mm thick, and backed by a gauze-like cloth that is tightly bonded to the leather to add strength while limiting stretch.” BUY IT ($999; $860) 7. Monte Matera ...
