What material are collection tubes typically made of?

• A. Wood
• B. Glass or plastic
• C. Metal
• D. Ceramic

Answer: (B)

Collection tubes are primarily made of glass or plastic due to their optimal characteristics for holding and preserving biological samples. Glass tubes are often used because they provide an inert surface that minimizes interaction with the sample, which is crucial for accurate testing and analysis. Additionally, glass is easily sterilized and allows for a clear view of the contents within the tube. Plastic tubes are also common, as they are lightweight, shatterproof, and can be produced in various colors to indicate different additives or types of tests. These materials are non-reactive, which helps prevent any chemical contamination of the samples, ensuring laboratory integrity and reliability. Other materials such as wood, metal, or ceramic do not possess the necessary properties for effectively collecting and storing biological samples. Wood can harbor contaminants and is not suitable for sterile environments. Metal could potentially interact with the samples, leading to erroneous results, while ceramic lacks the durability and practicality needed for safe handling and processing in a clinical setting.
