The Ultra Clean Vacuum Device or “U C V D ” patented by Mecoil is

ANSWER: ANSWER:

by Jim Fitch (Practicing Oil Analysis – Best Practices – July 1998) by Jim Fitch (Practicing Oil Analysis – Best Practices – July 1998)

The Ultra Clean Vacuum Device, or U.C.V.D. , patented by Mecoil is the ideal device for easy and simple oil sampling procedures. The UCVD is hassles‐free and avoids contamination, messes, or spilling. UCVD is hassles free and avoids contamination, messes, or spilling. Thanks to this innovative vacuum patented technology, the procedure for obtaining a realistic sample is ready at your fingertips!

Current procedures for: “Clean Oil Sampling” Clean Oil Sampling

Currently, it is recommended to use recommended to use a zip‐lock sandwich bag and tools like a bag and tools like a hand pump, in order to reduce the risk of to reduce the risk of cross‐contamination.
