Why is it important to maintain cleanliness in sample containers during oil sampling?

Maintaining cleanliness in sample containers during oil sampling is crucial primarily to avoid contamination. Clean containers ensure that the integrity of the oil sample is preserved and reflect the actual condition of the oil being analyzed. If contaminants such as dirt, dust, water, or other foreign substances enter the sample, they can significantly alter the properties of the oil, leading to inaccurate test results. Contamination can mask problems such as wear or excessive moisture, rendering the analysis invalid and potentially leading to incorrect maintenance decisions.

This focus on cleanliness directly impacts the reliability of laboratory results, which are essential for assessing the health of machinery and determining the appropriate maintenance actions. By starting with a clean container, the analysis reflects only the characteristics of the oil itself, allowing for better insights into its performance and condition. Thus, avoiding contamination is a fundamental aspect of successful oil sampling and analysis.
