What is ring stand?

A ring stand is a piece of laboratory equipment used to hold and support various types of glassware during experiments and observations. It consists of a vertical rod attached to a heavy, stable base, and a horizontal rod, often called a ring clamp, attached to the top of the vertical rod. The ring clamp can be adjusted to different heights along the vertical rod and is used to hold various types of glassware, such as test tubes, flasks, beakers, and graduated cylinders. Some ring stands also have additional attachments, such as clamps or clamping rods, to hold items that cannot be held by the ring clamp alone. Ring stands are essential components in many laboratory settings, including chemistry, physics, and biology.
