The sample bottle should be fully filled to ensure accuracy.

• A. False
• B. True
• C. It should be half full
• D. It should be three quarters full

Answer: (A)

The level of liquid in a sample bottle matters for preserving sample integrity and ensuring accurate results. Filling the bottle to the exact indicated level (often to a fill line or just below the neck) leaves a small headspace. That headspace helps with proper sealing, prevents leaks during transport, and accommodates any pressure changes or gas release without overflowing. It also ensures the preservative and any additives remain effective and that the sample volume matches what the method expects. Filling it completely removes this headspace and can lead to spills, sealing issues, or changes in the sample during transport, which can compromise accuracy. Therefore, the statement is not correct: you should follow the specified fill level rather than filling it to the very top.
