In chemistry, a retort stand, also called a clamp stand,[1] a ring stand,[2] or a support stand,[3] is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks.[4]
The typical ring stand consists of a heavy base and a vertical rod, both usually made of metal. A number of accessories, such as clamps of various types and iron rings, can be attached to the rod by thumbscrews, at whatever heights and orientations are necessary to support the target equipment.
