A rectangular hot plate is a laboratory heating device designed with an elongated, flat heating surface, typically made from durable materials such as aluminum or ceramic to ensure even heat distribution. It often features adjustable temperature controls, allowing precise regulation up to 350C. The hot plate is equipped with safety features such as overheat protection and a stable, corrosion-resistant construction. It is ideal for heating multiple samples simultaneously or larger vessels, making it suitable for applications in chemical reactions, sample preparation, and other laboratory processes that require consistent and uniform heating.
