Use the FILTER tool to scroll through the list of available analysis and/or supplies or use the SEARCH tool to type in bottle or test information.  

PRO TIP: Be mindful of the “Summary” column; it provides important information about required volumes, other tests that can be run out of the same bottle, additional supplies that may be requiredetc.   Not sure what size bottle you need for multiple parameters?   Click on the “Sample Volume Guide” for the minimum required volumes for all standard tests.  

STEP 2   –  Add the required bottles to your cart.   

Enter the quantity of each container, and click “Add to Cart”

PRO TIP: Make sure you have included any supplies that may be required for field treatment (for example 0.45 um filter and a syringe for dissolvable metals tests) in your order.  

Enter your payment information (if needed), shipping address, required date, and you’re on your way! 

What bottles should I order?

The “Order Bottles and Supplies” section below features a filterable table where you can search for containers by analysis or name.  To save you time in the field, refer to the “Sample Volume Guide” which will help you determine how much sample you actually need to submit for each test, and consider using a single bottle for multiple parameters.  

When can I expect the bottles to arrive?

Unless otherwise requested, our standard shipping time is 5 business days. If you are planning your sampling event for a specific date, please enter your desired delivery date in the “Due Date” field at checkout.  Please note that expedited shipping may be subject to a surcharge. 

Why am I being charged for bottles and/or supplies?

The charges associated with the various bottles and supplies cover the costs of these supplies as well as environmental disposal of your sample after it has been analyzed.   To remove these charges from your order, consider signing up for an account (see above) or apply a promotional code at checkout.   

Please note that some supplies, including Volatile Sampling Kits, Pump Rentals etc. carry charges that are associated with the calibration and maintenance of the equipment.  If you have questions about these charges, please Contact Us.  

What if I needed my bottle order YESTERDAY (we know, it happens!)

Incoming bottle orders are monitored by CARO staff on an ongoing basis during regular business hours.  If you need your bottles delivered in less than 24 hours, please place the order as per usual, and copy the confirmation number with your desired ETA in an email to [email protected]  

How will I know when my order is processed?

As soon as the order has been submitted, you will receive an email with an order confirmation number.  Additional notices will be sent by email when the order is being processed (we are actively working on assembling your order), and when it is shipped (complete with tracking details, so you are always in the know!)   

What if I don’t hear back?

If you don’t receive a message indicating that your order was received within 24 hours of submitting, please contact our team, and we would be glad to follow-up personally.  

PRO TIP: Before emailing, please venture through your junk mail and/or clutter box to ensure our message wasn’t filtered out (it most certainly isn’t junk!)
