Measure conductivity with BactoBox®

BactoBox® comes with a built-in electrical conductivity meter. Use the Conductivity program to measure the electrical conductivity of your vial.

Use the Conductivity program to, e.g., ensure that your Do-It-Yourself (DIY) diluent has the right conductivity.

Get things ready

You need these items:

• 1 × clean BactoBox® setup

• 2 × vials to measure on. Could be a dilution vial or a sample vial.

Clean the BactoBox® setup first

Make sure that you use a clean BactoBox® setup. See Clean.

Step by step

We run the Conductivity program twice (once for each vial). First, a trial run to avoid carry-over from the previous liquid. Then, a final run where we note down the result.

The disinfection vial has zero conductivity. Even a tiny carry-over from the disinfection vial has a large impact on the conductivity result. This is why the trial run is important.

1

Trial run

Transfer the tubing kit to the first vial.

Run the Conductivity program. You find it in the Programs menu.

Press and hold Measure for 1 second from the home screen to access the Programs menu.

Discard the result. This is only a trial run.

2

Final run

Transfer the tubing kit to the second vial.

Run the Conductivity program.

3

That is it!

Use the electrical conductivity from the final run.

Discard both vials.

Your sample vial is for single use only

Once you run the liquid through BactoBox®, the properties change significantly.

Always discard your sample vial after use!
