Sample bottles are small containers used to collect and store liquid or solid samples for testing and analysis. They are commonly made from materials like glass or plastic and come in various sizes, depending on the type of sample being collected. Sample bottles are essential in fields such as laboratory research, environmental testing, and food safety. These bottles often feature secure lids to prevent contamination and spillage. Some sample bottles are designed for specific purposes, such as sterile bottles for medical samples or amber bottles that protect light-sensitive substances. Proper labeling and handling of sample bottles are crucial for accurate results in testing.
