In order to be read by our scanning system, the samples must be labelled correctly. Improperly labelled samples could result in delayed processing, please follow the instructions below to ensure that your samples are optimized for an efficient run through our workflow.   Avoid delays in your sequencing data delivery by following our barcode labelling instructions below.  ######                     ORDERS SUBMITTED IN TUBES Please affix the barcode label so it is visible on the **front** of the 1.5 mL tube, as shown.   ######                     ORDERS SUBMITTED IN PLATES Please affix the barcode label to the **short right** side of the 96 well plate, as shown.   ## Sample Submission Guidelines For the best sequencing results, GENEWIZ strongly recommends you follow our [Sample Submission Guidelines](https://www.genewiz.com/en-gb/public/resources/sample-submission-guidelines/sanger-sequencing-sample-submission-guidelines) as closely as possible.    **QUESTIONS?** **call our Customer Support team** | ## Europe (non-UK) [genomics.service.europe@azenta.com](mailto:genomics.service.europe@azenta.com) +49 (0)341 520 122-41 | ## United Kingdom [genomics.service.uk@azenta.com](mailto:genomics.service.uk@azenta.com) +44 (0)1279 873 837 | | --- | --- |   [About Azenta](https://www.genewiz.com/Public/Company/About-Us)    [Contact Us](https://www.azenta.com/contact-us)    [Privacy Policy](https://www.azenta.com/privacy-statement) ©2024 Azenta Life Sciences
