Instructions For Collecting & Delivering Samples
Biotech Laboratory specializes in bacteria water tests and chemical water tests. (If you’re not sure what type of test you need, please see our FAQs or contact us.) We provide instructions for collecting bacteria and chemical samples so you can collect a sample and drop it off at our Chesterfield, VA, location; please contact us for the address.
We provide sterile containers for bacteria testing. For chemical samples, you can use a 6-12 oz clean drinking water bottle (your own or one we can provide). First time clients – please call prior to collecting or delivering a sample, to review instructions and to alleviate the need to resample or make multiple trips. If you are selling or purchasing property, please see our FAQs page for additional information. We can provide contact information for companies that collect and deliver samples as part of their service.
Step 1: Pick up materials. Supplies are available in our drop box, 24/7. This includes full instructions, drop-off form and collection containers.
2. Sterile Container
Step 2: Obtain a sterile container(s) from the top shelf.
These must be used for bacteria testing. For chemical testing, use a 6-12 oz clean drinking water bottle (your own or feel free to use one from the large cooler on the ground).

4. Collect The Sample
Step 4: Collect the sample. Detailed instructions are provided for sanitizing the faucet and flushing the line. Samples from the kitchen faucet are not recommended; samples from a bathtub faucet are preferred.
