Lab wire gauze is a piece of laboratory equipment used to support containers over a heat source. It is typically made of interwoven stainless steel wire mesh and is placed on top of a tripod or ring stand. The wire gauze provides a stable, heat-resistant surface for containers such as flasks, beakers, and test tubes, and helps to distribute heat evenly.

The wire gauze can also be used to protect the heat source from direct contact with the container, which can help to prevent breakage or other damage. In addition, lab wire gauze can be easily cleaned and reused, making it a cost-effective and convenient choice for many laboratory applications.
