Please use good sampling techniques. Our analyses are based on the sample submitted, which should be representative of larger batches or lots. Samples requiring special handling, treatment, or preparation may be subjected to additional charges.

We can preserve samples upon arrival at no additional cost; however, if we must split a sample into additional containers in order to accomplish proper preservation (i.e. multiple tests with different preservatives), container fees will be added. Air-sensitive or volatile samples should be submitted in separate vials for each analysis, if possible.

Additional sample return charges will apply for hazardous samples requiring non-standard packaging or shipping. Call for additional information.
