Sampling

Whether it is from a barrel or a large tank, taking a sample correctly is very important. The goal to proper sampling is to collect a sample that is representative of the tank or barrel that you are sampling from. If you are pulling a sample from a tank then collect it from the middle of the tank. If sampling from a barrel, either pull the sample from the middle or stir the barrel and then pull the sample.
