Apart from the button programs, BactoBox® has a few specialized programs.

Click the tabs to read more about the available programs.

{% tabs fullWidth="false" %}
{% tab title="Conductivity" %}
Select *Conductivity* to run a conductivity check.

The device reports electrical conductivity (EC) in µS/cm. The value is **not** temperature-compensated.
{% endtab %}

Run *Deep clean* to remove hard-to-clean deposits in the liquid path.

See [Deep clean explained](https://help.sbtinstruments.com/encyclopedia/maintenance/deep-clean).

{% tab title="Custom measurement" %}
Use *Custom measurement* for special gating settings (for example, endospores).

Create custom programs in BactoBox Explorer. Upload them via Access.
{% endtab %}

{% tab title="Measure with low conductivity" %}
Use *Measure with low conductivity* when you need extra contrast between intact cells and background.
