What containers should I use for my samples?

Many bulk samples can be placed in a zippered bag.  Clean glass jars are acceptable for liquids.   All containers should seal to prevent cross contamination.  If you are unsure, please contact  us.

How should I label my samples?

Each sample should have an unique ID which should be written on the sample (if applicable) or on its container.

How should I ship my samples?

Care should be taken in packaging the samples so that the samples arrive intact.  For instance, wrap glass jars in bubble wrap to prevent breakage.  Even concrete samples should be wrapped individually in bubble wrap to prevent damage. If you have other questions, please contact us.
