A test tube holder or rack is used in a laboratory to hold or support test tubes containing chemicals or other contents awaiting further operations. Although it is called a test tube holder, it is also used to hold/support pipettes, etc. Since a test tube has a rounded bottom, it cannot stand by itself; the rack is a convenient and necessary piece of laboratory equipment for the storage of test tubes.
