When filling a sample bottle before sending to NOAP, how full should it be filled?

When preparing a sample bottle for submission to the Navy Operational Analysis Program (NOAP), it is crucial to adhere to specific protocols regarding the fill level of the bottle. The procedure dictates that the bottle should be filled to a level that is precisely 1 milliliter below the rim or to the point of being full, ensuring that there is minimal air space above the liquid. This practice helps to prevent contamination and ensures the integrity of the sample during transport and analysis.

Filling the bottle incorrectly—either too full or too empty—could lead to issues such as leaks, contamination, or insufficient sample volume for testing. By adhering to the guideline of filling it to this specific volume, one ensures that the sample's quality is preserved, enabling accurate analysis and results.
