How Do I Pull an Oil Sample?

Authored by: Allan Zieser, STLE, CLS

We get it, it can seem overwhelming to try and pull an oil sample. But, we promise, once you learn how to correctly pull a sample, it will be easy to pull a sample correctly!

When pulling a sample, it is important to be mindful of many things that can affect the results if it isn’t done properly. Here are some common tips for pulling samples using a vacuum pump and bottle. This is one of the most common types of oil sampling in use today.

  • Cleanliness is as important as accuracy in sample pulling.
    • Always clean around the sample point before opening the machine or connecting the sample gun to the equipment.
    • Always use a new sample tubing section for each sample to avoid cross-contamination of the samples you are pulling.
  • Always fill out your sample forms as completely as possible. Be sure to include a unique name that will describe the equipment and sample point you are pulling the sample from.
  • Be sure and place the cap on the bottle as soon as you detach the sample bottle from the vacuum gun. Failure to do so can result in external contaminates getting in your sample and skewing your results.
  • Try and send in the results to the lab as soon as is possible. This will ensure that your sample matches the actual condition of the oil in the machine as closely as possible when the results come back to you.
  • Always contact your Ottsen Oil Expert if you have any questions on oil sample pulling.
