Beta Analytic’s Policy on Returning Archived Samples

Except for water samples, when a material submitted is sufficient in size to allow a small amount of excess original and/or pretreated sample to be archived, we will archive the sample for a few months following the time of reporting / release of results. This is done as an internal Quality Assurance measure to allow for back-up analyses or additional investigations to be performed, if needed.

Following this retention period, all sample bags and excess sample materials (original and pretreated) will be disposed by incineration.

Requests for Sample Returns

If you require the return of any unused original or pretreated excess sample materials, your request MUST be made in writing at the time of submission (we may not be able to honor later requests).

Please note on the online form that you want your extra samples returned. Alternatively, you can email us at

Please provide the shipping address and delivery option:

1. Regular US parcel post (costs may apply for heavy/international shipments)
