Tthis wire gauze is a durable square mesh made of galvanized or stainless steel, often featuring a ceramic-coated center. It is typically placed on a support ring or tripod stand beneath glassware to evenly distribute heat from a Bunsen burner or other heat sources, helping to prevent thermal shock and breakage of delicate lab equipment. The ceramic center enhances heat diffusion and offers additional protection to glassware by providing a more uniform heating surface. Ideal for chemistry, biology, and general science labs, wire gauze is a fundamental tool for any setup involving direct flame heating.
