A laboratory apparatus designed to hold and support multiple test tubes upright. These structures typically feature a series of evenly spaced holes or pegs, sized to accommodate the standard dimensions of common laboratory test tubes. The primary function of this equipment is to provide stability and prevent spillage or breakage during experiments, storage, and transportation of samples. For example, after a chemical reaction is conducted in a test tube, it can be placed within this device for observation or to await further analysis, eliminating the need for the tube to be held manually.
This item is essential for maintaining organization and efficiency in a scientific setting. By providing a designated space for each tube, it minimizes the risk of cross-contamination and allows for easy identification of individual samples. Historically, these holders were often constructed from wood, but modern versions are frequently made of plastic, metal, or other durable materials chosen for their chemical resistance and ease of cleaning. The implementation of this device streamlines laboratory workflows, reducing potential hazards and enhancing overall experimental accuracy.
