How do I get a sample of in-service lubricating grease analyzed?

Certain commercial laboratories specialize in the testing of in-service lubricants. Several of these laboratories analyze in-service lubricating grease.  These labs can be found through on-line searching.  Samples can be shipped via US Mail or other delivery services if packaged properly, or may even be delivered in person.  Contact a commercial lubricant testing laboratory for more information.
