A minimum of 24 hours advance notice is needed to put together bottle orders and have them shipped to your location. A standard charge of $20.00 per shipment will be assessed. Most bottle orders are shipped via UPS Ground. Should overnight service be required, additional charges will apply.

What types of bottles do I need?

The bottles that you need depend upon the type of analyses requested. For a complete listing of sample containers, preservation techniques, and holding times click here. To view the types of bottles we commonly use, click here. 

For a complete California Title 22 Analysis, the following bottles would be required (click here). If you have any questions, please contact your Project Manager.

What is your standard turnaround time?

Turnaround for analytical results will vary depending upon the analyte(s), matrix type, and the regulatory requirements for the samples submitted. In general, Babcock Labs provides test results within 10 working days.

What rush turnaround times are available?

Rush turnaround of samples depends upon the degree of sample prep and extraction that is required by the applicable methods. In general, Babcock Labs offers rush turnaround in 24, 48 and 72 hours as well as 1 week. All rush turnaround capability is dependent upon the current laboratory workload and requires prior laboratory approval.

Which commonly performed analyses have short holding times?

pH, chlorine residual: 15 minutes - best if performed on-site, Dissolved oxygen: 8 hours - if fixed on site, Hexavalent Chromium: 24 hours, BOD, Nitrate, Nitrite, Turbidity, MBAS, Orthophosphate, Settleable Solids: 48 hours, Microbiological analyses: (Drinking Water): 30 hours, (Wastewater): 8 hours, (Source water): 8 hours.

How can I locate more information about a particular analyte (Synonyms, Method Numbers, etc)?

We have found the web site to be very useful for this task.

Why are reporting limits sometimes elevated in a result?

The reporting limits that can be achieved on actual environmental samples can be influenced by a number of factors such as sample size, final extraction volume, injection volume, dilutions, instrument sensitivity, and matrix interferences. For example, if dilution of the sample is necessary due to matrix interference, the reporting limit must be adjusted to account for the dilution factor used. A ten-fold dilution will result in the reporting limit being elevated by a corresponding factor of ten.
