How It Works

Thank you for choosing CVAS as your feed and forage analysis lab!  We provide a wide range of testing options that can be found under our services menu or on our PRICE LIST information page.

Submitting samples is an easy process.  Please fill out an ACCOUNT APPLICATION and submit samples using our sample bags (more information below) or SAMPLE SUBMISSION form.

CVAS provides quart-sized sample bags at no charge. The sample bags have a form affixed that provides the user the opportunity to identify the sample and request services without additional paperwork. If you are submitting your sample using the mobile app or website for general information, please be sure to include your account number and Unique ID on the sample bag that was given during the submission process.

CVAS can provide poly shipping bags for shipping samples. These work for shipping samples by UPS and U.S. Mail. Shipping and sampling supplies can be found on our SUPPLY ORDER FORM. 

To order US Postal shipping labels and/or UPS shipping bags you may call us toll free at 1-800-282-7522, or email us at We request that you obtain Priority Mail shipping bags from your local Post Office.
