A laboratory apparatus designed to hold multiple test tubes upright. These racks provide stability and organization, preventing spills, breakage, and contamination of the tubes and their contents. The device commonly features a series of evenly spaced holes or slots designed to accommodate standard test tube sizes.
The utilization of these racks is crucial in chemical and biological laboratories for several reasons. They facilitate efficient workflows by keeping samples organized and easily accessible. The upright positioning minimizes the risk of accidental spills or cross-contamination between different samples. Historically, these racks have been a fundamental tool, evolving from simple wooden structures to modern designs incorporating materials like plastic, metal, or autoclavable polymers to meet the stringent demands of modern scientific research. Their use contributes to a safer and more productive laboratory environment.
