Sterile bottles are specially designed containers that are free from any living microorganisms. They are commonly used in laboratories, hospitals, and medical settings to ensure that samples, cultures, or medications remain uncontaminated. These bottles are often made from materials like glass or plastic and are sealed to maintain their sterility until they are opened. To achieve sterility, these bottles undergo processes such as autoclaving or gamma radiation. They are essential for various applications, including microbiological testing, pharmaceutical storage, and sample collection. Using sterile bottles helps prevent infections and ensures accurate results in scientific and medical procedures.
