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 UniqueID 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. Two sizes are available: 12 inch x 15.5 inch at $0.25 each and 19 inch x 24 inch at $0.70 each.
