Asbestos Sheet with Frame (DZ) is a high-quality laboratory accessory designed to provide reliable heat insulation and support during heating operations. It is commonly used as a base for flasks, beakers, and crucibles placed on tripod stands or wire gauze while using Bunsen burners. The asbestos sheet is securely mounted in a durable metal frame, ensuring rigidity, stability, and long service life. It effectively distributes heat evenly across its surface, preventing direct flame contact with glassware and reducing the risk of breakage.
