Information about Submitting Samples:
For a full grade/inspection we require 1000 to 1250 grams. For a protein test we need approximately 600 grams. For a Falling Number determination we need approximately 250 grams. For a DON or vomitoxin test we need approximately 200 grams. For an aflatoxin test we need approximately 10 pounds. These can be sent directly to our office at 404 Tower and we can usually give results the same day we receive the sample. Each sample should have an ID attached so the customer will recognize the results when received. The samples should also be accompanied by an address/fax number where the results can be sent.
