Prepare Samples
Always handle only one sample at a time. Begin and end the packaging process for each sample prior to beginning the next to avoid mix-ups.
Recommended sample sizes
Please read sample handling and container recommendations before preparing your samples
Package Samples for Shipment
Use small boxes instead of envelopes to protect the samples from being crushed or powdered during shipment.
For groundwater samples, please put the bottles inside a plastic bag and seal the bag with a zip-tie or duct tape. If any of the bottles leak during shipment, the water will not weaken the cardboard shipping container.
Please use a tracked mail service or courier and email the tracking number to lab@radiocarbon.com.
