Iron ring (laboratory)

An iron ring is a circular piece of laboratory equipment typically made of iron or steel, supported by a ring stand. It is used to support other laboratory apparatus, such as funnels, evaporating dishes, wire gauze, or clay triangles, during experiments involving heating or filtration. Iron rings come in various sizes, with diameters ranging from a few centimeters to larger sizes suitable for supporting larger objects. The ring is usually attached to the ring stand using a screw clamp that allows for vertical adjustment. The stability and adjustability of the iron ring are crucial for safely and effectively conducting a wide range of laboratory procedures. It is an essential component in many setups requiring controlled heating or secure support of labware.
