A Test Tube Stand is a laboratory apparatus used to hold and organize multiple test tubes in an upright position during experiments or while drying. It helps prevent test tubes from falling, spilling chemicals, or breaking. Test tube stands are commonly made from wood, plastic (polypropylene), or metal, and contain several holes on the top plate to hold test tubes securely. The base provides stability, and some models include pegs for drying inverted test tubes. They are widely used in chemistry, biology, and educational laboratories for arranging test tubes during experiments, observation, or storage.
