Laboratory racks are stand supports that hold, organize, and store test tubes, centrifuge tubes, vials, microtubes, pipette tips, and other containers in an upright position. The purpose of racks is to keep the samples apart and easy to access, which helps to avoid spillage and breakage. Laboratory racks have a broad application in various laboratories including pharmaceuticals, clinical, microbiological, biotechnological, chemical, and research labs. There are many types of laboratory racks depending on their capacity and material (plastic, metal).
