# Experiment Start

{% hint style="warning" %}
[Calibrate](https://khalil-lab.gitbook.io/evolver/getting-started/calibrations) your eVOLVER before beginning your experiment
{% endhint %}

When starting an experiment you'll go through the same process as a [normal experiment](https://khalil-lab.gitbook.io/evolver/experiments). Make sure that you have the extractor columns properly set up and that you also include the slow pumps lines in your line sterilization process.

{% hint style="info" %}
Preemptively check the troubleshooting [page](https://khalil-lab.gitbook.io/evolver/extensions/custom-experiments/extractor-column/broken-reference) to see common mistakes before running the experiment
