What’s inside your testing kit?

Sampling Instructions

Every test comes with step by step instructions on how to prepare your water source, collect your water sample, and prepare your sample for return shipment to our labs.

Collection Bottles

Your kit includes all the bottles, tubes or vials necessary to collect your water sample. For most kits, however, there is only one collection bottle needed.

Sample Information Card

Your kit includes a postcard that asks for a few details about how and where you collected your sample (i.e. kitchen faucet). Just fill it out, drop it in the return box, and we'll do the rest.

Prepaid Shipping Label

Shipping is always on us. This package includes a prepaid overnight shipping label to the lab. Just stick the provided label on the outside of the box and drop it in the mail.

Return Container (If Applicable)

Some of our tests require your water sample to be cold when it reaches our labs. If this applies to your test, the proper refrigeration items will be included.
