The test tube rack is the most basic experimental instrument in a chemistry lab. It is used to hold test tubes (sometimes to observe the progress of an experiment) and to allow them to dry. This rack consists of small wooden supports with tiny holes. A small hole allows the test tube to be placed vertically for use or to observe the progression of a reaction. A column, on the other hand, allows the cleaned test tube to be placed upside down to dry.
