A porcelain circular disc is a laboratory accessory used as a base or support for glassware and other containers during experiments. It is typically made of porcelain, a type of ceramic material that is able to withstand high temperatures and chemical corrosion.
The circular disc has a flat surface and is usually circular in shape, providing a stable base for glassware and other containers. Circular discs are commonly used in chemistry, pharmaceuticals, and other laboratory applications where the support of glassware and other containers is required.
The porcelain construction of the circular disc provides durability and resistance to chemical corrosion, making it a cost-effective solution for laboratory support.
