A retort stand is a type of laboratory equipment used to support a retort flask during experiments, particularly distillation processes. A retort stand typically consists of a base, a rod, and a clamp to secure the retort flask in place. The base provides stability for the stand, while the rod can be adjusted in height to accommodate the size of the retort flask and the experimental setup.

The clamp, which can be a boss head or a retort clamp, secures the retort flask to the rod, preventing it from tipping or falling. Retort stands are made of materials such as metal or plastic, and are designed to be durable and corrosion-resistant, suitable for use in various laboratory environments.

They are commonly used in chemistry, chemical engineering, and other laboratory settings, and are an important tool for conducting accurate and precise distillation experiments.
