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.
